Re: \du in psql patchp

Patch applied. I removed the reference to asprintf() and changed it to
a string constant. I have also added documentation changes. Patch
attached.

The new feature looks like:

test=> \du
List of Users
User Name | User ID | Attributes
-----------+---------+------------------------
demouser2 | 140 | create DB
postgres | 139 | create user, create DB

Very nice.
