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 ?

Looks indeed like a bug to me. Performing VALIDATE CONSTRAINT on what is
a non-inheritable constraint shouldn't look for that constraint in the
child tables. Attached patch fixes that. Should be applied in all of the
supported branches.
Thanks,
Amit

Should have included -hackers when posting the patch. Here it is again
for -hackers' perusal.
