ALTER TABLE ... REPLICA IDENTITY USING INDEX verified key columns by reading pg_attribute.attnotnull, but commita379061a22made attnotnull true also for unvalidated (NOT VALID) not-null constraints, which do not prove the column null-free. An index over such a column could thus be marked as replica identity even though the column might contain NULLs, causing apply-side divergence for UPDATE/DELETE on the nullable rows. Fix by additionally requiring convalidated for the underlying constraint, mirroring the fixd9ffc27291applied to ATExecAddIdentity for the analogous identity-column case.
