Re: Seeking performance advice and explanation for high I/O on 8.3

I attached a CSV of "select * from pg_stat_all_tables" from one of our
more heavily used databases. Note: I turned off stats collection and
autvacuuming a couple days ago to see what it would do and then
restarted postgres - I turned those back on this morning to that is why
there aren't more autovacuumed and autoanalyzed tables.

Sorry if this is a little verbose - I didn't want to leave anything out.
