[Dbmail] Size, vacuum, performance, etc

I'm hoping that someone on the list can help me sort out what I hope I'm doing wrong. Our group seems to be devoting a lot of time and heartache to running dbmail for our user base. Granted a lot seems to be database related. So if there is anyone on the list that is using dbmail 2.0 with Postgr

Jesse, I'm like you, there are only two of us here and we are learning PostgreSQL seat-of-pants style. Wow, then I'm completely lost looking at your numbers. I set my shmall and shmmax to 805306368, so that the DB (which is the only thing using memory on the box) could have 800M of shared RAM. A
