What I would rather see is that if the heap is vacuumed (whether or not by autovacuum) then the related TOAST table is also vacuumed (using the same horizon the heap used), but if the TOAST relation is chosen for vacuum by itself that it does not attempt to adjust the horizon based on old_snapshot_threshold. I am looking to see how to make that happen; expect a new patch Monday. -- Kevin Grittner EDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
