Re: [BUG] Fix DETACH with FK pointing to a partitioned table fails

After applying the attached, the r_1_p_id_fkey1 will have redundant action

triggers, as below:

postgres=# select oid, conname, contype, conrelid, conindid,conparentid, confrelid,conislocal,coninhcount, connoinherit from pg_constraint where oid = 16402;
  oid  |    conname     | contype | conrelid | conindid | conparentid | confrelid | conislocal | coninhcount | connoinherit
-------+----------------+---------+----------+----------+-------------+-----------+------------+-------------+--------------
 16402 | r_1_p_id_fkey1 | f       |    16394 |    16392 |           0 |     16389 | t          |           0 | f
(1 row)

postgres=# select oid, tgrelid, tgparentid, tgconstrrelid, tgconstrindid, tgconstraint from pg_trigger where tgconstraint = 16402;
  oid  | tgrelid | tgparentid | tgconstrrelid | tgconstrindid | tgconstraint
-------+---------+------------+---------------+---------------+--------------
 16403 |   16389 |      16400 |         16394 |         16392 |        16402
 16404 |   16389 |      16401 |         16394 |         16392 |        16402
 16422 |   16389 |          0 |         16394 |         16392 |        16402
 16423 |   16389 |          0 |         16394 |         16392 |        16402
