Tom Lane df1aa46285 Add missing buffer lock acquisition in GetTupleForTrigger(). ... If we had not been holding buffer pin continuously since the tuple was initially fetched by the UPDATE or DELETE query, it would be possible for VACUUM or a page-prune operation to move the tuple while we're trying to copy it. This would result in a garbage "old" tuple value being passed to an AFTER ROW UPDATE or AFTER ROW DELETE trigger. The preconditions for this are somewhat improbable, and the timing constraints are very tight; so it's not so surprising that this hasn't been reported from the field, even though the bug has been there a long time. Problem found by Andres Freund. Back-patch to all active branches.		13 years ago
