Actually, I think that code is not just under-tested but poorly thought
out.  It will dump ALL roles from a pre-9.5 database with NOBYPASSRLS;
even superusers.  I would think that existing superusers ought to be
assumed to have the BYPASSRLS property, no?  (This assumes that the
property means anything at all for superusers, which maybe it doesn't;
but if so we probably ought to be forcing it true for superusers to
avoid confusion.)
