Not sure why this thread is on pgadmin-support (general would be a
better place for it), but do note that as far as I know the log lines
you are referring to only indicate that autovacuum is processing the
database to see if it needs vacuuming -- there may not be any actual
vacuuming going on, because of, for example, your entries in the
pg_autovacuum system table.
