With commit a9f0e8e5a2e779a888988cb64479a6723f668c84, now pg_dump, use a bitmap to represent what to include. With this commit if non-super user is unable to perform the dump.
Hm. I think we need a src/bin/pg_dump/t/ test for the TAP suite for this one, because something this fundamental should really have blown the buildfarm up when committed.
