Title: Re: [PERFORM] upgraded to pgsql 8.2.4, getting worse performance then 7.4.x

Absolutely!

A summary of relevant comments so far are:
- enable-mergejoin
- shared-buffers
- fsync

Another to consider if you use indexes is random-page-cost.

What would be helpful is if you could identify a slow query and post the explain analyze here.

The concurrent performance of many users should just be faster with 8.2, so I'd think it's a problem with plans.

I didn't realize that. I'll have to harass the rest of the team to see if
someone overwrote that file or not. In the interim, I did an 'initdb' to
another location on the same box and then copied those values into the config
file. That's cool to do, I assume?

Cowering in a closet is starting to seem like a reasonable plan.
