Ok, so the deal is to finally reduce the locks to ShareRowExclusiveLock for the following commands : - CREATE TRIGGER - ALTER TABLE ENABLE/DISABLE - ALTER TABLE ADD CONSTRAINT
Correct. I personally still find this useful enough to justify a patch.
Looking at the latest patch, it seems that in AlterTableGetLockLevel@tablecmds.c we ought to put AT_ReAddConstraint, AT_AddConstraintRecurse and AT_ProcessedConstraint under the same banner as AT_AddConstraint. Thoughts?
Good point. I think moving those would be a good thing even though it is technically not necessary for AT_AddConstraintRecurse, since that one should only be related to check constraints.
