Not really, at the moment.  Sorry.  It's supposed to be coming soon
(see my other message about PITR).

No, it's not normal.  I think some additional digging is needed.

One thing that is important is to make sure your pg_dump doesn't
cause swapping on the machine.  Causing swapping is easy if you have
been too aggressive in shared-memory allocation for the postmaster,
and your OS is careless about who gets to be a candidate for paging.
(Solaris 7.1 without priority paging was subject to this problem, for
instance).
