All modern operating systems do this without any extra effort on your
part...all you can really do is get in the way.

Just make sure there is enough ram in the box and let postgresql do
its thing. I think in your case the only thing you should be
considering is to turn fsync on (safe, slow, default) or off (unsafe,
fast).
