title: Django: create database user on user-create
body: <p>I need to implement a functionality that creates a postgres DB-user when a django-user is created in the admin interface (DB-user should have same username and password).
  I figured out that I could use Signals to execute a script when a user is created, but the problem is I cannot get the raw password of the user.</p>
  
  <p>So is there a way to get the raw password of a django user in this context?
  And if not, what would be the best way to implement this functionality?</p>
