I'm not sure if you've done this for a later version of pg_autovacuum.
I'm using what came with postgres-7.4.6.  For database security on
a shared server (~800 logins) it's best to set the superuser password
and not allow passwordless connections.  The only thing is that
pg_autovacuum keeps the password supplied on the commandline so
anyone that does a 'ps' can get the database superuser password.

I hope that this is a worthwhile patch.
