We are still actively working on PgNext: The Next PostgreSQL Conference. The folks on the organizing team have been an invaluable resource at helping us determine the direction of the conference. We have also been receiving a lot of emails thanking us for the selection of Denver as the location, many of them from new attendees. If you haven't submitted a talk yet, now is the time!
The FKLocks patch was unfortunately pushed to 9.3 due to some outstanding issues not the least of which was a performance regression under normal FK use. This is a large patch that team member Alvaro Herrera has been working on for a very long time. It is a patch that has the potential to greatly increase the performance of foreign keys. It has been a lesson in patience, evaluation of sponsored work (it was partially, and only partially sponsored), and resource allocation. Hopefully we can be done with this soon.
