There's been talk of dropping pg_dump's support for dumping from pre-7.3
servers, as that would allow removing quite a lot of crufty and no longer
well-tested code. (7.3 is an interesting cutoff because that release
introduced both schema support and pg_depend dependency tracking.)
Not sure when we will get around to that, but it seems likely to happen at
some point.
