Having a WITH OIDS specification should result in the creation of an OID column, but commit b943f502b broke that in the case that there were LIKE tables without OIDS. Commentary in that patch makes it look like this was intentional, but if so it was based on a faulty reading of what inheritance does: the parent tables can add an OID column, but they can't subtract one. AFAICS, the behavior ought to be that you get an OID column if any of the inherited tables, LIKE tables, or WITH clause ask for one. Also, revert that patch's unnecessary split of transformCreateStmt's loop over the tableElts list into two passes. That seems to have been based on a misunderstanding as well: we already have two-pass processing here, we don't need three passes. Per bug #14474 from Jeff Dafoe. Back-patch to 9.6 where the misbehavior was introduced. Report: https://postgr.es/m/20161222145304.25620.47445@wrigleys.postgresql.org
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".
