Right; a genuine dependency analysis would be better. Also a lot more
painful to implement.

As you say, pg_dump could do with a wholesale rewrite, and maybe that
would be a good time to look at the dependency-based approach. In the
meantime, I think dumping in OID order would fix 90% of the problem for
10% of the work...
