I fixed that, and the basic regression tests no longer crash outright with
these settings, but I do see half a dozen errors that all seem to be in
RLS-related tests. They all look like something is trying to access an
already-closed relcache entry, much like the problem in
rebuild_relation(). But I have no time to look closer for the next
several days. Stephen, I think this is your turf anyway.
