Well, that was an interesting couple of days. Unfortunately my birthday came right after and I didn’t feel like writing anything for the duration. Now though? Why not!

A few months ago, Greg Smith of PostgreSQL fame suggested I submit a proposal to the new Postgres Open conference here in Chicago.

Ah, query hints. For all those times when the database isn’t doing what you want, they’re a useful tool for forcing the query optimizer to perform your bidding.

With the introduction of PostgreSQL 8.4, Bruce Momjian, a significant core developer, contributed a tool that can actually upgrade an entire database cluster in place. The time required is essentially only that necessary to copy the data files from the old installation to the new one. On a quick RAID system, this can be an order of magnitude faster than a dump/restore. The main drawback is similar to Slony: disk space must effectively be doubled for this upgrade method.
