Hi Mariano -- I'd like to encourage you to keep making pg8000 a viable alternative for web2py. I started with it but had to change to psycopg2 because of some issues that postgres handled better under the psy driver. But I think pypy could be the future of python and it won't support a driver like psycopg2 -- but it could support pg8000 since it is all python.
It's just good to have an alternative because no driver does it all. -- Joe B.
