Alvaro Herrera cb3a7c2b95 ALTER TABLE: skip FK validation when it's safe to do so ... We already skip rewriting the table in these cases, but we still force a whole table scan to validate the data. This can be skipped, and thus we can make the whole ALTER TABLE operation just do some catalog touches instead of scanning the table, when these two conditions hold: (a) Old and new pg_constraint.conpfeqop match exactly. This is actually stronger than needed; we could loosen things by way of operator families, but it'd require a lot more effort. (b) The functions, if any, implementing a cast from the foreign type to the primary opcintype are the same. For this purpose, we can consider a binary coercion equivalent to an exact type match. When the opcintype is polymorphic, require that the old and new foreign types match exactly. (Since ri_triggers.c does use the executor, the stronger check for polymorphic types is no mere future-proofing. However, no core type exercises its necessity.) Author: Noah Misch Committer's note: catalog version bumped due to change of the Constraint node. I can't actually find any way to have such a node in a stored rule, but given that we have "out" support for them, better be safe.		2012-02-27 19:10:24 -03:00
