Hello hackers! The commit 14e87ff added pg_constraint rows for not-null [1]. The consequence of the patch is that it changed the order of InvokeObjectPostAlterHook() call and update of "attnotnull" field in the catalog. Before the update was before the call of the hook [2]. And now "attnotnull" is updated after the call of InvokeObjectPostAlterHook() [3].
This is a noticeable change to extensions which use "object_access_hook" since they see a bit of stale information about the attribute. Is this an intended behavior or rather a bug? 1 - https://postgr.es/m/[email protected] 2 - https://github.com/postgres/postgres/blob/REL_17_9/src/backend/commands/tablecmds.c#L7818 3 - https://github.com/postgres/postgres/blob/REL_18_1/src/backend/commands/tablecmds.c#L8043-L8047 -- Kind regards, Artur
