I fail to understand the issue here. I tested the scenario both with and
without the patch,
and the behavior remained the same in both cases. While testing without the
patch,
I ensured that I created valid constraints.

I ran the script below with and without the patch, and the output was the
same in both cases.

------------------------------------------------------------------

CREATE TABLE parted (id bigint default 1,id_abc bigint) PARTITION BY LIST
(id);
alter TABLE parted add CONSTRAINT dummy_constr not null id;
select conrelid::regclass, conname, conislocal
from pg_constraint where conname = 'dummy_constr';

CREATE TABLE parted_1 (id bigint default 1,id_abc bigint);
alter TABLE parted_1 add CONSTRAINT dummy_constr not null id;

select conrelid::regclass, conname, conislocal
from pg_constraint where conname = 'dummy_constr';

ALTER TABLE parted ATTACH PARTITION parted_1 FOR VALUES IN ('1');

select conrelid::regclass, conname, conislocal
from pg_constraint where conname = 'dummy_constr';

------------------------------------------------------------------

Are we expecting *conislocal* status to be different when it's NOT NULL NOT
VALID?
