Ditto what Alvaro said.

However, you can get some measure of tracking my running VACUUM VERBOSE
on a regular basis to see how well autovacuum is keeping up.  There's
no problem with running manual vacuum and autovacuum together, and you'll
be able to gather _some_ information about how well autovacuum is
keeping up.
