When creating a foreign key in a partitioned table, if some partitions already have equivalent constraints, we wastefully create duplicates of the constraints instead of attaching to the existing ones. That's inconsistent with the de-duplication that is applied when a table is attached as a partition. To fix, reuse the FK-cloning code instead of having a separate code path. Backpatch to Postgres 11. This is a subtle behavior change, but surely a welcome one since there's no use in having duplicate foreign keys. Discovered by Álvaro Herrera while thinking about a different problem reported by Jesper Pedersen (bug #15587).

PostgreSQL tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check".
