No, autovacuum is doing this with every run. Beside this, the database has
only some 10k changes per day. The wraparound was my first idea, but i
don't see a reason, why this should be happen with every autovacuum run.

Most of this tables are just big (guestbook or forum entries as example).
But there will be no dead tuples, since the entries are inserted and never
changed. The main reason for putting this tables into the pg_autovacuum
table was to avoid the locks at all with normal autovacuum processing
and analyze the tables in a nightly maintenance window.
Kind regards
