Role support

["Dave Page" <dpage(at)vale-housing(dot)co(dot)uk>]

Hi Andreas,

Are you planning on working on role support in pgAdmin? 

With that, and the finished Slony 1.1+ support, perhaps we should
consider a release around the same time as pg8.1 (well, a little before
so we can include it in pgInstaller). What do you think?

Regards, Dave
