Isn't this a bit pre-mature as we still support running pg_dump against
8.0 clusters..?

Removing support for older clusters is certainly something we can
discuss but I don't know that it makes sense to just piecemeal pull
things out.  I get that this was just a documentation note, but, still,
we do support pg_dump run against 8.0 and 8.1 clusters, at least today.

Thanks,

Stephen
