* bogus error message for ALTER TABLE ALTER CONSTRAINT
@ 2025-03-04 18:22 Álvaro Herrera <[email protected]>

I just discovered that trying to set a foreign key as NO INHERIT in
ALTER TABLE ALTER CONSTRAINT returns an absurd error message:

create table pk (a int primary key);
create table fk (a int references pk);

alter table fk alter constraint fk_a_fkey deferrable, alter constraint fk_a_fkey no inherit;
ERROR:  ALTER CONSTRAINT statement constraints cannot be marked NO INHERIT

The explanation is that somebody misunderstood what must be given to
processCASbits in 2013.  The intended message is:
  ERROR:  FOREIGN KEY constraints cannot be marked NO INHERIT

Here's the fix along with some additional cleanup.

Subject: [PATCH] Fix ALTER TABLE error message

This bogus error message was introduced in 2013 by commit f177cbfe676d,
because of misunderstanding the processCASbits() API; at the time, no
test cases were added that would be affected by this change.  Only in
ca87c415e2fc was one added (along with a couple of typos), with an XXX
note that the error message was bogus.  Fix the whole, add some test
cases.

Backpatch all the way back.
