based on the irc chat here: http://www.tismer.com/pypy/irc-logs/pypy/pypy.2011-11-02.log.html PyByteArray_Type, PyMemoryView_Type and PyInterpreterState are missing from the headers. http://codepad.org/FYkhcZKf just wonder is there any schedule about this? I think psycopg2 is crucial for many developers to adopt pypy. thanks!
