This means that everything is going as expected: connection has been
requested in ascii and obtained so. I'll check if really the encoding
errors happen inconsistently in the fetch*() methods. What I suspect
is that you issued fetchone() and got an ascii-only record: if you
continued to loop on the entire recordset you'd eventually get an
error. Try (without setting the encoding to utf8):

    cur.execute("select [ your stuff, including non-ascii records")
    while 1:
        record = cur.fetchone()
        if not record:
            break

I'm pretty sure you will get an encoding error too.

I don't see anything wrong here. The only question is what is setting
the connection to SQL_ASCII. Maybe something in postgresql.conf or a
setting of the database user. It's not a psycopg issue anyway: the
driver is following the instructions.
