There isn't any especially good way to do it with the RPM packages
(at least not the ones from Red Hat or PGDG), because you can't
concurrently install different versions. In practice the old pg_dump
should work fine for this purpose in practically all cases, so it's
not worth your trouble to try to figure out a workaround.
(I am hoping that in 9.0 we have a better upgrade path for RPM
installations.)
