-Z 0 should mean no compression.
Something you can try is piping the output of pg_dump to gzip/bzip2. On
some OSes, that will let you utilize 1 CPU for just the compression. If
you wanted to get even fancier, there is a parallelized version of bzip2
out there, which should let you use all your CPUs.
Or if you don't care about disk IO bandwidth, just compress after the
fact (though, that could just put you in a situation where pg_dump
becomes bandwidth constrained).
