Commit 5a2fed911 had an unexpected side-effect: the parallel worker launched for the new test case would fail if it couldn't use a superuser-reserved connection slot. The reason that test failed while all our pre-existing ones worked is that the connection privilege tests in InitPostgres had been based on the superuserness of the leader's AuthenticatedUserId, but after the rearrangements of 5a2fed911 we were testing the superuserness of CurrentUserId, which the new test case deliberately made to be a non-superuser. This all seems very accidental and probably not the behavior we really want, but a security patch is no time to be redesigning things. Pending some discussion about desirable semantics, hack it so that InitPostgres continues to pay attention to the superuserness of AuthenticatedUserId when starting a parallel worker.
