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.</p> <p>Speaker: Paul Jungwirth</p> <p>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.</p> <p>[1] <a href="https://www.meetup.com/pdxpug/events/270062132/">https://www.meetup.com/pdxpug/events/270062132/</a> [2] <a href="https://jitsi.org">https://jitsi.org</a></p> </div> <h3>Links</h3> <ul> <li><a class="url u-url" href="https://www.meetup.com/pdxpug/events/270062132/">Website</a></li> </ul> </div>
