I love pgsql as much as anybody, and I generally don't run the latest
release in production until it's about 6 months out of the gate.
Between testing and approval and upgrading all the systems that aren't
production, by the time a new version sees production it pretty much has
to be 4 to 6 months old.
I also tend to run every other version. I've run 7.2, then 7.4, then
8.1. I've tested and played with 8.2 and speed wise, it wasn't a
compelling enough upgrade to start the very long process of replacing
8.1 with. By the time 8.3 comes out, I'll be about ready to start
evaluating our next version of pgsql.
I have to say the update to 8.1 was very compelling, as the query
optimizer was much better, and the ability to use indexes on date
columns with references like now() - interval '5 days' was a huge thing
for my reporting apps.
