During ALTER TABLE ATTACH PARTITION, if the name of a parent's foreign key constraint is already used on the partition, the code tries to choose another one before the FK attributes list has been populated, so the resulting constraint name was "<relname>__fkey" instead of "<relname>_<attrs>_fkey". Repair, and add a test case. Backpatch to 12. In 11, the code to attach a partition was not smart enough to cope with conflicting constraint names, so the problem doesn't exist there.
