Reference users for postgresql

Hi.

I would like to get a list of companies using postgresql, preferably
well known. I have found a list at http://www.pgsql.com/user_gallery/
, but to me it seems to have a extremely poor signal to noise ratio.

This list will give us an good argument in the discussion of whether
we should choose postgresql or a "well known commercial DB".
(Internally my group has met a lot of resistance in the choice of a
Linux system with postgresql over a win2k with sqlserver. We have now
finally managed to convince the management that Linux is the right os for this
application, but now they have started to argue that postgresql is a
crappy DB with no "real" users.)

Thanks.
