\du in psql patch

Hi everyone,

I quickly put together a patch to psql that allows one to view current
system users. The code is very simple, but it seems to work.

The usage is as follows:

database=# \du [username]

I apologize in advance for my lack of C skills, and I will gladly
accept any criticism or advice. I'm hoping I can figure out a way
to write an equivalent for groups, once I determine how to
get around the grolist integer[] column in pg_group.

Please take a look at the patch and see if it's worth anything.

Thanks

Alex
