Hmm, was looking in the manual and found "if" but it didn't say anything about 
those two.

Anyway, also don't really know the "proper" way to determine if it's 
installed. So figured anytime there's a "data" dir, postgres must have been 
initialized, so that's why I picked "-d". At the time didn't know about the 
"-e".

Really though, flying by the pant seats and plagiarizing the heck from other 
modules :)
