Well, there are various filesystem add-ons that allow you to have
virtual partitions spread over one or more physical disks. I'm guessing
you're not using any of those.
You can move the WAL to a different disk and use table-spaces to
relocate tables and indexes. See the manuals for tablespace setup and
check the mailing-list archives for how to do it the hard way with
symbolic links if you're running an old version of PG.
