I will try. The error happens when running the "First Steps" demo program at http://www.rmunn.com/sqlalchemy-tutorial/tutorial.html exactly at the "users.create()" statement. The connection string looks a bit different here though: db = create_engine('postgres://username:[EMAIL PROTECTED]:5432/mydatabase') I have postgresql-8.1 (8.1.4-4) installed. It's a Sarge server that I dist-ugpraded to Etch today. It happens both with python2.3 and python2.4.
