That was true back in the 6.x days, but starting in 7.1 we had code in
pg_dump to work with a 7.0 server, and we've kept up that policy.
Perhaps you are thinking of pg_dumpall specifically? That was a shell
script until 7.3, and before it was converted to C I don't think it had
much of any cross-version adaptability.
