PostgreSQL Users' Group monthly meeting. Followed by refreshments at the Lucky Lab.

Topic: Visual Planner Presenter: Tom Raney, PSU Where: FreeGeek, 1731 SE 10th Avenue, Portland, OR When: 7pm, September 18, 2008

Tom Raney will be presenting the Visual Planner, a GUI tool written in Java that enables the user to peek inside the PostgreSQL planner's decision making process. The tool shows all plans that were evaluated including the plan that was picked for execution. Tom worked on this during Google Summer of Code, and credits Dr. Len Shapiro, a professor at Portland State University and PDXPUG regular, as a great help.

Tom showed off his tool during OSCON and has gotten some feedback from community members on it. He's working up a test example that should appeal to DBAs, and I'll link directly to the source code once he's got it ready.

This work also involves a patch to PostgreSQL, which should be available soon!

After the meeting, retire to the Lucky Lab for refreshments!

Join us for the second annual PostgreSQL Conference West! Scheduled to begin October 10 and go through the weekend, West being held at Portland State University is going to be the destination for learning, fun and general education about PostgreSQL.

2nd THURSDAY OF EACH MONTH, BEGINNING JANUARY 8, 7:00 PM PORTLAND STATE UNIVERSITY, 1900 SW 4th AVENUE, FOURTH AVENUE BUILDING – ROOM 86-01

See website for more details.

Monthly meeting of the Portland PostgreSQL Users' Group.

Ed Borasky will be speaking about Data Visualization.

Beers after at the Lucky Lab on Hawthorne.

Sponsored by the Computer Science Department, Portland State University

This series will consist of 5 to 6 presentations aimed at PostgreSQL database users who wish to learn more about tuning their systems for performance. Attendees will learn how to generate and interpret operating system (Linux) and database statistics, and the effects of some system tuning techniques. This involves studying the well known Online Transaction Processing (OLTP) benchmark called TPC-C ( www.tpc.org ). TPC-C was developed by a committee, representing all major players in the database marketplace, to be representative of typical online enterprise databases. TPC-C consists of a precisely defined schema and 19 queries. We will review the schema and queries and demonstrate how each tuning technique affects their performance. We will use an open source package that the speaker has developed, called DBT-2, which many DBAs have found useful.

by Len Shapiro

Abstract: I'll survey how I teach the introductory database course at PSU. My goal for the talk is to elicit suggestions for how I could do a better job. The theme of the course is "transforming data into Information". I use a 200 Meg database, hosted on PostgreSQL, instead of the one-slide databases used in typical intro courses, to illustrate the principles of the course. The database is Federal Elections Commission data re donations to candidates, so queries often reflect real questions about the real data.

Bio: Len Shapiro has been a professor at PSU for 23 years. His research interests are primarily in query processing.

Webb Sprague will be speaking about PostGIS and the Census Data at the next PDXPUG meeting at FreeGeek (at 7:00pm - 1731 SE 10th Avenue, Portland, OR).

Looking forward to seeing everyone there....and of course, drinks at the Lucky Lab http://www.luckylab.com/ ) at 915 SE Hawthorne Blvd. afterwards.

More details from Webb:

If anyone is wondering about specifics, I will describe how I recently created a "crosswalk" table that correlates census tracts in 1980 with census tracts in 2000 in the Portland region (well, Washington, Multnomah, and Clackamas counties), so that we could see poverty trends over the last 25 years.

I used PostGIS, Census naming conventions ("FIPS codes"), and lots of outer joins. So if you like that sort of thing, I would love to hear your comments tomorrow!

Location-based services are all the rage these days, and almost everyone has a latitude and longitude or two stashed away in a numeric column somewhere. But, there is so much more to it than just a point. Once relegated to government and academia, geographic information systems are becoming increasingly visible. With the PostGIS extension, PostgreSQL is a first-class geodatabase and an incredible platform for working with spatial data, but what is PostGIS and why would one use it? And beyond PostGIS there are a dizzying array of tools to load, visualize and interact with the wonderful geospatial information in your database. This talk will cover GIS and PostGIS basics and provide an introduction to geodatabases and spatial queries.

Edwin Knuth spent quite some time as a sysadmin and web developer before going back to school to study Environmental Science at the University of Alaska Southeast. He quickly became fascinated with Geographic Information Systems and realized that GIS was just a really neat database application. In Alaska, Edwin worked on several unique projects, including building bat detectors and using PostGIS to manage a wireless sensor network on the Juneau Icefield. He has lived in Portland for the past year and loves it very much.

When: 7-9pm Thu Apr 21, 2011 Where: FreeGeek Who: David Wheeler What: Distributing Extensions on PGXN

So you've solved a common problem in PostgreSQL, a serious pain point that lots of other people could take advantage of. You want to open-source the code, and would like to package it up and distribute it where people can find it, read its docs, and download and install it.

The newest destination for distributing PostgreSQL extensions is PGXN, the PostgreSQL Extension network. PGXN offers a central index of PostgreSQL extensions and their documentation, making it easy for people to find an install extensions.

How do you optimize your extension distribution for maximum PGXN exposure? By careful packaging, thorough documentation, and simple installation. Join me for an overview of how best to achieve that — including how to build extensions compatible with PostgreSQL 9.1's improved extension support.

David Wheeler is an associate at PGExperts, and is responsible for PGXN, the PostgreSQL Extension Network) and pgTAP. He's into testing and extension distribution.

Beer afterwards at the Lucky Lab. See you there!

Normally, Gabrielle ensures that we have thoughtful and informative presentations. Unfortunately for you, I -- Melissa -- am guest-hosting this month.

What I'll come up with is anyone's guess, but BYOB is strongly recommended. Muahahaha.

Oh, and we may also talk about Postgres or something. And we'll join those folks at the Lucky Lab afterwards.

This month's topic is "Data Visualization and Exploration Techniques Using R and Postgres" with PSU's Dr Christopher Monsere.

Yes, it's ok to show up just for the afternoon (or the party) if your flight arrives on Sunday.

We'd like a $30 donation to SPI for the sessions, but don't let lack of funds deter you from attending.

Rob Wultsch, a recent addition to Facebook's Database Operations team, will compare and contrast the Facebook deployment with his previous work with another large deployment of open source databases. In this db-agnostic talk, he'll go over: the bizarre becoming ordinary, the many types of infrastructure that do not scale and what does and does not work when building a DBA team.

Before joining Facebook, Rob worked for a very large hosting company as a database administrator and a newspaper as a web developer. In his free time he enjoys riding his motorcycle and bicycle and fantasizes about moving to Portland.

As always, beer afterwards at the Lucky Lab. See you there!

Autovacuum’s like a Roomba, right? You just turn it on and it does all the work for you. Well, not quite – for one, your pets can’t ride around on it – and occasionally it may get stuck in a (figurative) corner. In this talk, we’ll discuss vacuum, analyze, and their daemonic counterparts: how to adjust them to perform appropriately*, and perhaps more importantly, what the heck are they actually doing?

This is a beginner-to-intermediate level talk, but you will learn something new about vacuuming, regardless.** –

Amazon integrated Postgres into their general Relational Database Services (RDS) offerings July 1, 2014. RDS offers automatic failover, scalability, and easy configuration, plus Amazon handles all the patching and upgrades for you! Their SDK supports many languages and includes a robust CLI, if you want to automate management of your deployments. They also support several popular Postgres extensions.

Of course, since it’s a managed service, you can’t do everything you might expect or want to. In this talk, I’ll discuss the fun, the quirky, and the downright maddening features I’ve discovered working with production RDS deployments. Come find out what it’s like to use RDS Postgres day-to-day.

Want automated high availability PostgreSQL without relying on someone else's cloud service? It's possible today, and easier than you think; we just need a little container orchestration pixiedust, and your DBAs can take the weekend off.

Josh Berkus will explain the current state of HA Postgres services on Kubernetes/OpenShift, introducing the several projects in this area, and then going into a deep dive on Patroni/Spilo. He'll bring you up to date on the new "Kube-native" Patroni, and work expected in the future. With live demos!

Josh Berkus helps manage the Kubernetes community for Red Hat. He is a "hacker emeritus" for PostgreSQL. He lives in NE Portland with a large black cat, a pottery studio, and a librarian.

Ahoy database folk! Time for another meetup and more container chit chat. Yeah yeah, you, like me, have heard that you shouldn’t run databases in containers. Well without throwing all caution to the wind, I’m hoping to show you guys some container workflows with Postgres that I’ve been using lately. We’ll talk a bit about why you haven’t been running databases in containers, then walk through some development work flows with Postgres, and lastly look at options for deploying and running persistent databases in containers.

Temporal databases let you record history: either a history of the database (what the table used to say), a history of the thing itself (what it used to be), or both at once. The theory of temporal databases goes back to the 90s, but standardization has only just begun with some modest recommendations in SQL:2011, and database products (including Postgres) are still missing major functionality.

This talk will cover how temporal tables are structured, how they are queried and updated, what SQL:2011 offers (and doesn't), what functionality Postgres has already, and what remains to be built.

Paul started programming on a Tandy 1000 at age 8 and hasn't been able to stop since. He helped build one of the Mac's first web servers in 1994 and has founded software companies in politics and technical hiring. He works as an independent consultant specializing in Rails, Postgres, and Chef.

Speaker: Hannah Stepanek

Let’s talk databases in python! What’s an ORM? Is there a way to write database queries so that they are compatible with multiple types of databases? How do you make database changes (such as adding a new table or a new column) safely? What is a connection pool and why is it useful? What are some things that can go wrong when operating at scale? In this talk we’ll take a deep dive into how the python libraries sqlalchemy and alembic make managing production databases simple, efficient, and painless so you can get back to feature development.

Hannah has been working in industry for over 6 years as a python software engineer. She currently works at Hypothesis, a web application for annotating web pages and pdfs. In her spare time she enjoys riding her horse Sophie and playing board games.

Speaker: Grant Holly

This month I will be demonstrating using non-blocking IO database access using Scala and the Slick library. No really, the library is called Slick AND it is very cool to use. Slick and Scala are great for working with Postgres with either straight SQL, or using the FRM (that’s a Functional Relation Mapper like in functional programming). After Hannah gave a great talk talk about Python, Postgres, and ORMs, I got to thinking that I could do a language and ORM talk. Thanks Hannah, that was great.

Hi, it’s me still Grant. I work at New Relic as an engineer on the database engineering team. I’ve been using Postgres in production since 9.2 and have been using and enjoying Scala for about two years having worked on a couple of production high throughput applications.

Learn about the considerations in planning for disaster recovery in order to maintain business continuity. There are solutions available that can help you achieve your backup and recovery objectives by taking advantage of PostgreSQL features, such as point-in-time recovery, and help implement retention policies.

Also learn how to take advantage of PostgreSQL’s replication features to keep your database highly-available, and the basic cluster architectures to consider to keep a PostgreSQL cluster up and running.

Speaker: Will McLean

To follow the presentations on accessing Postgres from Python and Scala, I will lead a discussion on accessing Postgres with Java. I'll start with a jdbc tutorial and finish with adding data access to a springboot webapp.

I have twenty years experience in e-commerce applications, the last eight here in Portland, mostly at Nike.For the last few years everything has been moving to Amazon RDS Postgres, that's a trend pdxpug can get behind! I am currently working for Navis on CRM applications for the hospitality industry.

Jackson will discuss the basics of GIS, and the current environment in which enterprise spatial analytics are performed. Considering the many pitfalls of this current system, he will discuss how FOSS tools – especially PostgreSQL/PostGIS – are vitally important for modern spatial analytics. In addition to the PostGIS extension, Jackson will talk about network routing using the PgRouting extension and the interface between R and PostgreSQL. This talk will act more as a showcase of GIS and “spatial SQL” within PostgreSQL than it will nitty-gritty database development.

Jackson Voelkel is a Health Data Analyst on Kaiser Permanente’s GIS Team as well as an Adjunct Professor of Geography at Portland State University. He focuses on developing infrastructure for and performing advanced spatial analytics across healthcare, environment, urban planning, utilities, and econometrics. He teaches courses on advanced spatial analytics in R as well as spatial database design with PostgreSQL/PostGIS.

This month I am going to be talking about my current work on sharding large mysql databases with Vitess. My team has been on a journey towards splitting our largest mysql databases and I want to share my experiences and lessons learned. We are going to look at the problems and possible solutions to scaling reads and writes in relational databases.

Vitess is an open source project born at youtube to scale their largest and most critical databases. It has been adopted in as a Cloud Native Compute Foundation incubator project. With PostgreSQL on the medium-term road map, let’s take a look at what we have been able to do with mysql.

Hi its me Grant. I work on the database engineering team at New Relic. I’ve been using Postgres in production since 9.2. I co-organize the Postgres user group in Portland with Mark Wong.

pg_top was born in 2007 from a fork of the unixtop, a terminal program displaying top processes on the system, where pg_top focuses on the processes with the PostgreSQL database you are connected to. Recently pg_systat was forked from systat to display additional database statistics.

These tools have can help do more such as explore query execution plans and create reports from system and database resources.

Come learn about the statistics PostgreSQL keeps and how to use these tools to view them.

Speaker: Alex Theodore

As a CTO I saw everything that went into and came out of the web development process, from the "client needs" to the source-controlled code. But being skilled in database development showed me time and time again that databases (and their architecture) were often sidelined treated as after-thoughts and often times served as little more than flexible storage spaces. Yet, their contents were the very essence of value for the process/client/company being served. This strange inversion of priorities led me to develop a way of looking at databases as "outside" the application and ultimately to interacting with them as API's. In my talk I'll be presenting this concept and showing with simple rules and examples how it can be done.

Bio:

I was the product and technology founder of Fracture.me and CTO up until 2018 where I developed the manufacturing processes and ERP software that powered our production process. That got me deeply involved in database work, especially with architecture and process design and optimization. Now I work part time as a database consultant and part time building modern, minimalistic furniture for my new (small) company MillFinish.com.

Speakers: Gabrielle Roth & Michelle Franz

In February, long-term PDXPUGers Michelle Franz & Gabrielle Roth return to discuss DBLINK and FDW, two methods of accessing data that’s outside your database. We’ll briefly mention SQL/MED on the way, and tell a couple of bad (Dad) jokes.

We’ll cover use (and mis-use) cases, configuration of each, and interesting quirks. Gabrielle will attempt a live demo of file_fdw and postgres_fdw. You’re welcome to follow along if you’d like, just show up with a couple of Pg databases: they can be on the same cluster (or container or RDS instance or what have you) or different ones, doesn’t really matter. One of them should have at least one table with data in it.

About the speakers:

From embedded systems to UI to relational database programming, Michelle’s running an interesting path through the software world. Working with databases is her current episode, with some programming, some DBA, some SysAdmin and a healthy dose of learning agile. She’s very quickly come to appreciate and enjoy working with Postgres and her work has allowed her to learn from some super talented database experts.

Gabrielle has been using Postgres since sometime in the version 7s, and thinks that the best part of using Open Source software is the culture of sharing knowledge. She’s a Senior Data Engineer at NS1 and co-founder and former co-lead of PDXPUG.

We are using Meetup.com to distribute the link to the online meeting [1], which will be set shortly before the meeting as we will be using Jitsi [2]. Meetup does require you to RSVP to get access to the link. Jitsi can be used directly with Firefox and Chrome (with extension), or phones/tablets with the Jitsi Meet app.

Speaker: Paul Jungwirth

I'd like to present a couple patches I have in-progress for Postgres, the first to add a new type called "multiranges", and the second to add various SQL:2011 temporal database features: temporal primary & foreign keys, and temporal UPDATE and DELETE. I'll discuss what these features look like to users and also highlight some of the implementation details behind them.

PostgreSQL 15 was released on October 13, 2022 so let's give it a look!

We will shamelessly use a presentation readily available on the internet to see all the newness in this latest release.

Come learn what's new, share experiences with changes, or just meet with local peers! Casual, informal.

Getting started with Django is a delight. However, as your application grows, that sqlite database you start with can become a limitation. We are going to look at how to wire up a new Django project to Postgres, and we will talk about some of the neat features in Postgres and Django that you can utilize including JSON, UDFs/procs, and extensions to name a few.

Hopefully you can pick a few ideas, or even share your own with the group. This talk is for all levels of experience from “I just heard about Django” to “We run production Django”, from “oh Postgres, that’s the elephant one right?” to “Ask me anything about Postgres”.

We will also have zoom link available closer to the presentation date if you want to attend remotely. Sign up on MeetUp for this notification: https://www.meetup.com/pdxpug/events/293519969/

Few abstractions and tools have proved as enduring in the field of Computer Science as the relational database model. Due to the diligent efforts of the Postgres team, the Postgres project has an ever increasing popularity in the software world and a fully modernized feature set. One effect of the longevity of the project has been to create a deep pool of received wisdom regarding the use and misuse of Data Models and SQL. Revisit some of the wisdom from a classic of the genre: SQL Antipatterns: Avoiding the Pitfalls of Database Programming by Bill Karwin, with updated opinions and commentary to modernize the material. Stay after for pizza and a rousing exchange of ideas on the past, present, and future of SQL and of the Postgres project.

Speaker: Jerry Sievert

Extensions are part of what makes Postgres such a powerful and popular database. Being able to add new capabilities to your database allows developers to adapt Postgres to many different use cases from geospatial (PostGIS), to multi-server sharding (Citus), to custom datatypes (pg_semver), to foreign data wrappers (postgres_fdw), and others.

Jerry is going to walk us through getting started working on database extensions. We will cover how extensions work and getting started authoring your very own first database extension! Time permitting, and with interest, we will cover operators and types. This talk is intended for all developers and DBA’s alike, so bring your questions. If you have a favorite extension, we want to know, so bring it to the discussion. I’ll go first: favorite extension: most flavors of FDW’s for sure.

Now a bit about Jerry. He’s currently working at Hydra (https://hydra.so/) on data warehousing with Postgres, but has been using Postgres for waaaay too long. If you’ve ever used PLJS (https://github.com/plv8/pljs), he’s the author, and he is the maintainer of PLV8 (https://plv8.github.io/).

PostgreSQL 16 was released on September 14, 2023 so let's give it a look!

We will shamelessly use a presentation readily available on the internet to see all the newness in this latest release.

Come learn what's new, share experiences with changes, or just meet with local peers! Casual, informal.

Note that this will be the last PDXPUG meeting of the year until 2024.

Speaker: Grant Holly

Moving a live production dataset between servers is hard to do. I’m going to share a few examples of how I’ve been able to move data and workloads between servers without downtime, dropped writes, or stale reads. I had to break out more than a few Postgres tricks like logical replication, foreign data wrappers, and writable views, all of which we will be reviewing.

My goal is to share a few strategies that have worked and how they handle the common difficulties with moving live datasets. Please bring your own stories and questions and add to the conversation.

PostgreSQL 17 is in feature freeze. The expected release date is sometime this September.

We will review freely available presentations available on the internet to see what we can can expect in the next major release.

Come learn what's new, share experiences with changes, or just meet with local peers! Casual, informal.

Please RSVP in the MeetUp link to help us gauge expected attendance. https://www.meetup.com/pdxpug/events/300096141/

Speaker: Paul Jungwirth

Benchmarking is an important part of developing database systems like Postgres. For businesses, benchmarking can guide important decisions around selecting a database management system, or evaluate configuration changes. However, while there are many standard benchmarks out there, setting up, configuring, running, and collecting results was left as an exercise to the reader.

Benchbase is an open-source benchmarking framework from Carnegie Melon University’s Database Group (https://github.com/cmu-db/benchbase). It helps you configure, run, and collect results from various standard benchmarks. It also provides a framework for authoring your own performance benchmarks, and wiring it up to the batteries-included configuration, running, and results collection provided by it.

Paul is going to walk us through Benchbase, and some recent work he has embarked on around creating a benchmark. If you are a veteran of benchmarking, or have never done a benchmark before, this talk is for everyone.

Now a bit about Paul. He’s a freelance software developer here in Portland, and has been building applications with Postgres since 2011. Paul has been working on the Postgres project itself. He’s authored many database extensions, and his contributions to Postgres include work on GiST indexes, multiranges, and SQL:2011 application-time features.
