This was my first thought.  After about an hour of running, I stopped the
process, edited the schema file to remove all the foreign keys and triggers.
I then started it again.  So there SHOULD be no triggers right now.

UPDATE:  I stopped the restore, before it was stopped, top showed postmaster
using 17% CPU.  After stopping I noticed that it DID fill my largest table
(1.16 M tuples) over night.  So I am editing the dump file to continue where
it left off. ( vi is the only thing that is not choking on the 2.4 gig file)
That is good news because that means it wont take 7-10 days to import, just
1-2.

As for version (oops) my old version was 7.3.1 and I am moving to 7.3.2

Any other ideas?

Oh, a bit off topic... I remember that I wanted to move the WAL files off of
the raid but forgot to do it on start up.  Can I do that now that the system
is setup?  Where would I find docs to tell me about that?
