Oh, you're right --- so I was mistaken to claim it had always been like
that. Before we started using array_to_string here, you *could* tell
the difference between default privileges and no privileges.
The precedent of previous versions makes it more plausible that we
should print '{}' for no privileges, but I'm still not quite convinced.
Anybody else have an opinion?
