Postgres bonobo controls

[Vivien Malerba <malerba linuxave net>]

Hi!

I've just commited the postgres bonobo controls. They include  the framework to
update each other. Unfortunately, there is still some work to be done on it,
the controls are still a little buggy, and I won't have time do to it before
tuesday. 

So, Rodrigo, if you could wait until wednesday to make the new release, I would
have time to polish that a little.

Cheers!

Vivien
