I created to run psycopg2 on Python 3.0, at http://www.dcl.hpi.uni-potsdam.de/home/loewis/psycopg_3k.diff I also submitted the patch to Frederico di Gregorio, who will integrate it when he finds time. The patch passes nearly all tests (the failures seem unrelated, since the unmodified code also fails in nearly the same way). Regards, Martin
