postgres patches

I guess if people do not do the +1 stuff, a patch for Rails is never
picked up. So, if you use Postgres and want things to work nicer than
they currently do, please check out:

http://dev.rubyonrails.org/ticket/9042

and its associated Railities patch:

http://dev.rubyonrails.org/ticket/9045

I've used these for six months now. If you use them and like them, do
the +1.

Thanks,
