When you say "direction of shortest path" are you referring to human 
readable text driving directions?

If so there currently is no function in pgRouting that does that. I have 
discussed this in some detail on the list (check the archives), and how 
it can be implemented. I have implemented this:
http://imaptools.com:8080/maps/dd2.html?lat=34.53886&lon=69.15786&zoom=13&layers=B00TFTTTF&start=69.144741%2034.547085&stop=69.172264%2034.531735&method=STS&lang=eng
but is dependent on the structure of the data tables you load and use. 
There is a lot more information in the archives explain how this was done.
