BUG #17930: Regression in DISABLE TRIGGER ALL

The following bug has been logged on the website:

Description:

Hi!

The following script creates a partition table with a foreign key and works
fine on PostgreSQL 14:

begin;
create table a(id int primary key);
create table b(id int primary key, a_id int not null references a(id))
partition by range(id);
create table b_default(like b including defaults including constraints);
alter table b attach partition b_default default;
alter table b disable trigger all;
commit;

On PostgresSQL 15, it fails on DISABLE TRIGGER ALL:

ERROR: trigger "RI_ConstraintTrigger_c_20196703" for table "b_default" does
not exist

It seems to use a wrong trigger name. In this case,
RI_ConstraintTrigger_c_20196703 is the name of a trigger defined on the
parent table b.

Thank you.
