I believe it's not enabled by default in 8.1-land, and is as of 8.2
and later.  Whether it's running or not, try "SELECT * FROM
pg_autovacuum;".  If that returns the null set, it's not doing
anything, as it hasn't been told it has anything to do.

IME, however, if you really want to benefit from the autovacuum
daemon, you probably do want to be on something more recent than 8.1.
(And, yes, this is a bit of the pot calling the kettle black: I have a
mixed set of 8.1 and 8.3 hosts.  Autovacuum is only running on the
latter, while the former are queued for an upgrade.)

You are right, autovacuum is not running after all. From your comment, I am wondering if you'd recommend I turn it on or not? If so, given that I doubt I will upgrade any time soon, how would I enable it? I suppose I could google that, but google rarely shares gotcha's. :)
