How smaller? Remember that I have got a 1GB RAM... and even if I run it
on a smaller RAM machine... that would mean checking MBs of tuples
anyway... I don't think checking manually tuples one by one would be a
good choice in my case.

Do you have one?

I suppose that the current postgresql sorting module works. As I said
I'm just creating a patch to get better (faster, more efficient) the
actual sorting module.
