Having just re-installed postgres from the postgres website I can say that Josh's suggestion does work. I tried a few long random strings of characters which it wouldn't accept, but the auto-generated one is WAY more random - make sure you write it down, though (I took a screenshot because it has a couple of really wierd characters I didn't want to mistake, to type it out I had to resort to Word's Insert-character option!).
