Recent PostgreSQL Optimizer Improvements
Tom Lane, Red Hat, Inc.

Track: PostgreSQL
Date: Thursday, July 10
Time: 2:30pm - 3:15pm
Location: Salon A

Lane describes recent work on PostgreSQL's query planner/optimizer. Topics include: what the optimizer does and how it does it, JOIN ordering, IN/NOT-IN optimization, equality propagation, and other changes scheduled to appear in the upcoming 7.4 release. This session appeals to both to geeks who want to know about the innards of the optimizer, and to ordinary mortals who just want to make their queries go faster.
