title: Is there a simple way to delete all members from a role
body: <p>I have a user defined role called OrderEntry in my database that only has two members.  Dropping them individually to in turn drop the role isn't a big deal. However I can see this being an issue if the situation arose where you needed to drop a role and needed to delete all members from that role first.  Is there a simple way to do that for future reference.  I'm thinking in terms of SQL script</p>
