Alvaro Herrera b40776d221 Have CLUSTER advance the table's relfrozenxid. The new frozen point is the ... FreezeXid introduced in a recent commit, so there isn't any data loss in this approach. Doing it causes ALTER TABLE (or rather, the forms of it that cause a full table rewrite) to be affected as well. In this case, the frozen point is RecentXmin, because after the rewrite all the tuples are relabeled with the rewriting transaction's Xid. TOAST tables are fixed automatically as well, as fallout of the way they were already being handled in the respective code paths. With this patch, there is no longer need to VACUUM tables for Xid wraparound purposes that have been cleaned up via TRUNCATE or CLUSTER.		2007-05-18 23:19:42 +00:00
