Cool! Thanks for your effort.

I'll have a look in the next day or two, still recovering from Easter
holidays :o)

As for Twisted, I have a half-done implementation. I'll open a ticket in

PS: If things work out well I think I'll try to submit a lightning talk
for PGCon 2010 about PG, Python, psycopg2 and Twisted. That should at
