This is probably not what you want to do - there are less drastic ways to
get more performance out of PostgreSQL. One thing you can do is move
your WAL files to a different disk, as they are very heavily accessed.
(this is the pg_xlog directory). There are lots of other things that can
help as well - post your hardware and/or queries to the performance list
and you should get some good responses:
