Hi, Matthew. For our uses, we found that pg_autovacuum did not behave
as expected with vacuum_threshold set to 0. For our purposes, we have
a very good idea of how many tuples need to be slurped up over a given
interval, and would like the autovacuum daemon to simply go through and
vacuum when it hits a, er, threshold.
Obligatory explanation: We were doing this with cron, but when
something gets really ugly, cron is not as intuitive as autovacuum.
Having this in the postmaster would be fine by me (and in fact, I would
even suggest that it belongs there), but I really need to have more
flexibility or we are going to (read: I will be tasked with) be writing
our own.
Sorry for the terseness -- and I haven't had a chance to go over the
whole thread; we're moving from 7.3.2 to 7.4.2 on "the big database"
this week.
