When you say upgrading, how'd you upgrade? Source upgrade, or is it a
build from scratch (CD install)? If it's a build from scratch, I'd
run through tuning(7) and enable soft-updates if they're not already
on. When you say it's slower, it sounds like disk-access is slower.
Have you tuned the postgresql config? -sc
