Here's a nice summary of the power supply options, courtesy of the old Beavis Audio website.
The one thing I would add to Induction's excellent summary above is that many older schematics (e.g. fuzz faces) don't have any power filtering at all because they were designed to work with a battery only. Power filtering is much more of an issue with modern effects which need more current and hence rely on "wall warts" and similar power supplies.
Also note that many power supplies for effects are rated for 9.6V. This is to accommodate the voltage drop due to an inline resistor or diode.
