Yeah, we've discussed that before, and I wouldn't mind explicitly ripping
out support for pre-7.3 or pre-7.4 servers; we could get rid of a pretty
fair amount of cruft in pg_dump with such a policy change. But right now
the standard is 7.0 and I don't want that goalpost moving silently.

(And yeah, I did just test it back to 7.0. But that depends on my HPPA
box which is looking increasingly frail. I'm not sure that we can get
versions that old to compile on more modern platforms, at least not
without a lot more work than it's probably worth.)
