It supports servers back to 7.0. At some point we ought to consciously
desupport old servers and pull out the corresponding code, but that
needs to be an act of intention not omission ;-)

(It's entirely likely that the 7.0 server I keep around for testing this
is the last one in captivity anywhere. But IIRC, we've heard fairly
recent reports of people still using 7.2. We'd have to desupport before
7.3 to save any meaningful amount of pg_dump code, so I'm not convinced
it's time to pull the trigger on this quite yet.)
