-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I think that SQLAlchemy behaves incorrectly when there is a primary key constraint on multiple columns and one of the columns is of type Integer.
## from sqlalchemy import schema, types, create_engine metadata = schema.MetaData() test = schema.Table( 'test', metadata, schema.Column('x', types.String, nullable=False), schema.Column('y', types.Integer, nullable=False), schema.PrimaryKeyConstraint('x', 'y') ) engine = create_engine('postgresql://...', echo=True) try: metadata.create_all(engine) finally: metadata.drop_all(engine) ## The generated TABLE statament is: CREATE TABLE test ( x VARCHAR NOT NULL, y SERIAL NOT NULL, PRIMARY KEY (x, y) ) In my opinion, autoincrement should be assumed to be true *only* when there is one primary key of type Integer.
