postgresql setup question

[Jude DaShiell <jdashiel@shellworld.net>]

I managed to make the postgresql cluster with initdb but can't do anything 
with createuser because postgresql by default is trying to use a unix 
socket at address 5432.  I'm running on amd hardware and don't know what 
needs to be done to either enable this socket or go with another 
alternative so this socket problem goes away.  In earlier notes I had used 
to set up earlier versions of postgresql which I used to try to set 8.3 up 
I didn't have this problem so am wondering what additional information I 
need.
