Er, what "user/password issue"? Context please.

The datdba is not necessarily a superuser, and therefore is absolutely
not the right answer for any question related to autovacuum. But in
any case, I would expect that an integrated-into-the-backend autovac
implementation would be operating at a level below any permission checks
--- so this question shouldn't be relevant anyway.
