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
