[BUGS] BUG #14629: ALTER TABLE VALIDATE CONSTRAINTS does not obey NO INHERITclause

The following bug has been logged on the website:

Bug reference:      14629
Logged by:          Hans Buschmann
Email address:      buschmann@nidsa.net
PostgreSQL version: 9.6.2
Operating system:   Windows x64
Description:


Given these both tables (orders_archiv inherits orders) on 9.6.2 Windows
x64
(cut/paste from psql)

xxxdb=# \d orders_archiv;
...
Check constraints:   "ck_or_old" CHECK (or_season < 24) NO INHERIT
Inherits: orders


xxxdb=# \d orders
...
Check constraints:   "ck_or_new" CHECK (or_season >= 24) NO INHERIT NOT VALID
Triggers:   tr_orders_insert BEFORE INSERT ON orders FOR EACH ROW WHEN
(new.or_season < 24) EXECUTE PROCEDURE fn_orders_insert()
Number of child tables: 1 (Use \d+ to list them.)


When applying these commands to the parent table, the following errors are
returned:

xxxdb=# alter table orders validate constraint ck_or_new;
ERROR:  constraint "ck_or_new" of relation "orders_archiv" does not exist


xxxdb=# alter table only orders validate constraint ck_or_new;
ERROR:  constraint must be validated on child tables too

Background:
From our original partitioning of quite a lot of tables according to
xx_season columns (a season is a half year period) I dropped and recreated
the check constraintsin a not valid state.

At the end of the script to move the data from 2 seasons into the archiv
tables I tried to reenable the check constraints and encountered those two
errors.

It seems that I can circumvent these errors by recreating the constraints
without the not valid clause.

Do I miss something here ?
