This September will bring us the release of PostgreSQL 9.3. To celebrate this, PostgresXC hacker Michael Paquier will be in town (visiting from Japan), and will give us a short talk on Background Workers. He and Josh Berkus will also talk about some of 9.3's other features. Josh will demonstrate abusing Cascading Replication.
This meetup will be hosted by SwitchFly (http://www.switchfly.com/), the #1 backend for flight bookings for multiple travel sites.
Food and Drink is sponsored by Arun at Sunsson (http://www.sunsson.com). Need a Postgres job or a Postgres employee? Contact them.
There will be Live Video of this meetup for the benefit of the intertube public. Video will be on Ustream (http://www.ustream.tv/channel/sfpug). Video is likely to begin around 7:30PM PDT.
For those of you who can attend, there will be giveaways and auctions of stuff at this meetup, including "Keep Calm" posters, stickers, and possible other swag.
