Is there any permissions issue involved here? I'd be a bit worried
about whether \dn+ could fail, or deliver misleading answers, when
run by a user without permissions on (some) tables. Also, even if
we allow people to get size info on tables they can't read today,
having this feature would be a roadblock to tightening that in
the future.
