How to: freeRADIUS with PostgreSQL Backend!

[Just E. Mail]

I have setup a working freeRADIUS server & now want to add PostgreSQL as 
backend for storage of data. I have read the freeRADIUS documentation 
and researched the internet on this subject.

What I am looking for is any kind of Step-by-Step document detailing 
sequential steps needed to setup a PostgreSQL back end for freeRADIUS. 
Has someone written such a document? Is there such a writeup available?
