I tried raising it to 16384, but I can't seem to find a relationship
between shared_buffers and performance level for this server.
My findings are pretty much the same here. I don't see any link
between shared buffers and performance. I'm still looking for hard
evidence to rebut this point. Lower shared buffers leaves more
memory for what really matters, which is sorting.

An upgrade to 8.1 is definitely the way to go.
Any 8.0 - 8.1 migration advice?
If you are getting ready to stage an upgrade, you definately will want
to test on 8.2 and 8.1. 8.2 might give you better results in the lab,
and has some nice features.
