Refreshing findoidjoins for v11

Hi all,

Wouldn't it be time to update the list of catalog joins generated by
findoidjoins?  Running it myself, I have spotted two new links:
+Join pg_catalog.pg_constraint.conparentid => pg_catalog.pg_constraint.oid
+Join pg_catalog.pg_partitioned_table.partdefid => pg_catalog.pg_class.oid

86f5759 has already updated oidjoins.sql for the first join but forgot
the updates in findoidjoins, and the second is still missing.

Please find attached a patch to refresh all that.

Thanks,
