I've not attempted running cx_oracle itself with Python 3 at all, and haven't
made any attempt to test SQLAlchemy's dialect with python 3 + cx_Oracle.
What happens if you run a plain cx_Oracle script in Python 3 that runs the
equivalent statement, that is,
import cx_Oracle
conn = cx_Oracle.connect(username, password, dsn)
cursor = conn.cursor()
cursor.execute("insert into users (id, name, extra) values (:id, :name,
:extra)", {"extra":2013, "name": "Ed Jones", "id": 2})
