This does not really mean that autovacuum has done anything in the
databases. If the times are consistently separated by 1 min, then it's
possible that it always exits without doing anything.
In such old a release we didn't have any decent logging mechanism in
autovacuum :-( You can change log_min_messages to debug2 to see if it
actually does anything or not.
I suggest you connect to the problem database (and then to all others,
just to be sure) and run "vacuum" (no full).
