pg_autovacuum is a daemon, not something that get's run twice a day.
I think that's what the question Matthew was getting @. I'm not sure
what would happen to performance if pg_autovacuum was launched twice a
day from cron, but you could end up in an ugly situation if it starts
up.

I'll work on theses issues:
we have space for more ram(we use 2 gigs on possibility of 3 gigs)
iowait is very high 98% --> look like postgresql wait for io access
raid5 -->raid0 if i'm right raid5 use 4 writes(parity,data, etc) for
each
write on disk
use more transactions (we have a lot of insert/update without
transaction).
cpu look like not running very hard
*php is not running on the same machine
*redhat enterprise 3.0 ES
*the version of postgresql is 7.3.4(using RHDB from redhat)
*pg_autovacuum running at 12 and 24 hour each day
What do you mean by "pg_autovacuum running at 12 and 24 hour each
day"?
I suspect he means at 1200 and 2400 each day (i.e noon and midnight).
