Of course, the counter-argument is that people who are still using those
versions are probably not going to be interested in upgrading to a
modern version anyway.  Or if they are, dumping with their existing
version of pg_dump is likely to not be much worse than dumping with the
target version's pg_dump --- as Robert mentioned upthread, if you're
migrating from such an old version you're in for a lot of compatibility
issues anyhow, most of which pg_dump can't save you from.

Having said that, I'm not in a hurry to pull pg_dump support for old
versions.  But we can't keep it up forever.  In particular, once that
old HPUX box dies, I'm not likely to want to try to get 7.0 to compile
on a newer box just so I can keep checking pg_dump compatibility.
