Any given table can only be in one tablespace.
Usually people with this type of issue set up their disks using LVM or
something similar, so that they can add space into an existing
filesystem. Another possibility (not mutually exclusive) is to set up
a partitioned table structure. Unfortunately neither of these solutions
is easy to bolt on after the fact :-(
