If you're planning on having a database larger than your file-system supports,
you might want to consider a different file-system. However...

Each object (table, index) is stored in a separate file (more than one if
split at 1GB). Some people use symlinks to move various files/directories to
different locations. For example, to move the write-ahead-log to a different
set of disks from the main DB files.

Tablespaces are being worked on at the moment, so there is a good chance they
will be in 7.5
