It is handled by autovacuum. What we do is, we schedule a manual VACUUM ANALYZE nightly job on bigger tables to avoid burden on the autovacuum during the business time.

If the DELETES are rare and are not deleting much, then frequent VACUUM FULL is not ideal. Regards, Venkata Balaji N Fujitsu Australia
