Hmm, I thought this would be obvious.  Vacuumdb just issues "VACUUM"
commands.

I would like the get the functionality if autovacuum so that I don't
waste cycles on tables that don't really need vacuuming.  However, we've
had bad luck letting autovacuum run on its own terms, so we've reverted
to the old nightly vacuums.

Since our nightly window of relative inactivity continues to shrink, I'd
like to vacuum/analyze only the tables that autovacuum thinks need it,
all at once, and only when I tell it to (via cron).

Make more sense?
