cvs.postgresql.org is not running bind at all - what it is using are two 
(purely) recursive resolvers upstream. One of them is only going to get 
upgraded tomorrow(some changes need to be rolled out in a staged 
fashion) the other one was done a while ago - I have simply removed that 
one from the resolv.conf for the time being.
