The docs show:
http://www.postgresql.org/docs/9.1/interactive/app-pgdump.html
-Z 0..9
--compress=0..9
Specify the compression level to use. Zero means no compression. For the
custom archive format, this specifies compression of individual table-data
segments, and the default is to compress at a moderate level. For plain text
output, setting a nonzero compression level causes the entire output file to be
compressed, as though it had been fed through gzip; but the default is not to
compress. The tar archive format currently does not support compression at all.
