Might be useful to profile why that is. I don't think pg_dump has
historically been developed with CPU efficiency in mind.
It's not pg_dump that is the problem - it is COPY that is the limit. In
my specific case als the fact that a lot of the columns are bytea adds
to the horrible CPU overhead (fixed in 9.0). Still our bulk load &
unload performance is still way slower on a per core comparision than a
lot of other databases :(
