Hi,
While reviewing the foreign keys referencing partitioned tables patch, I
noticed that the parentConstr argument of ATAddForeignConstraint is
rendered useless by the following commit:
commit 0325d7a5957ba39a0dce90835ab54a08ab8bf762
Author: Alvaro Herrera <alvhe...@alvh.no-ip.org>
Date: Fri Jan 18 14:49:40 2019 -0300
Fix creation of duplicate foreign keys on partitions
Above commit added another function specialized for recursively adding a
given foreign key constraint to partitions, so ATAddForeignConstraint is
no longer called recursively.
Maybe remove that argument in HEAD ? Attached a patch.
Thanks,
Amit
