Time flies when you're benchmarking. I noticed today that it's been over a month since my last blog post, so it's past time for an update. One of the great things about the PostgreSQL community is that it is full of smart people. One of them is my colleague Pavan Deolasee, who came up with a great idea for reducing contention on one of PostgreSQL's most heavily-trafficked locks: ProcArrayLock. Heikki Linnakangas (another really smart guy, who is also a colleague of mine) did some more work on the patch, and then I cleaned it up further and committed it.
