Add regression tests for constraint errors in partitioned tables.
While #16293 only applied to 11 (and 10 to some degree), it seems best to add tests to all branches with partitioning support. Reported-By: Daniel WM Author: Andres Freund Bug: #16293 Discussion: https://postgr.es/m/16293-26f5777d10143a66@postgresql.org Backpatch: 10-
