Subject: pgsql: SET NOT NULL: Call object-alter hook only after the catalog chan
Date: Fri, 20 Mar 2026 13:42:40 +0000
Message-ID: <E1w3a7b-000eG8-1e@gemulon.postgresql.org> (raw)
SET NOT NULL: Call object-alter hook only after the catalog change
... otherwise, the function invoked by the hook might consult the
catalog and not see that the new constraint exists.
This relies on set_attnotnull doing CommandCounterIncrement()
after successfully modifying the catalog.
Oversight in commit 14e87ffa5c54.
