That did the trick, thanks.
Well, actually, it did the trick for PostgreSQL but sqlite isn't
rolling back. The SA logs show the same commands are being sent to
both. Here's an example:
$ rm test1.sqlite
$ python sa_create_table_transaction_test.py
2009-02-06 13:39:29,006 INFO sqlalchemy.engine.base.Engine.0x..d0
BEGIN
2009-02-06 13:39:29,007 INFO sqlalchemy.engine.base.Engine.0x..d0
CREATE TABLE table1 (
col1 INTEGER
)
2009-02-06 13:39:29,007 INFO sqlalchemy.engine.base.Engine.0x..d0 {}
2009-02-06 13:39:29,021 INFO sqlalchemy.engine.base.Engine.0x..d0
CREATE TABLE table2 (
col1 INTEGER
)
2009-02-06 13:39:29,021 INFO sqlalchemy.engine.base.Engine.0x..d0 {}
2009-02-06 13:39:29,024 INFO sqlalchemy.engine.base.Engine.0x..d0
CREATE TABLE table2 (
col1 INTEGER
)
2009-02-06 13:39:29,024 INFO sqlalchemy.engine.base.Engine.0x..d0 {}
2009-02-06 13:39:29,027 INFO sqlalchemy.engine.base.Engine.0x..d0
ROLLBACK
$ sqlite3 test1.sqlite

And the updated test script:
# ----
import sqlalchemy as sa
engine = sa.create_engine('sqlite:///test1.sqlite')
#engine = sa.create_engine('postgres://localhost/test1')
engine.echo = True
metadata = sa.MetaData()
table1 = sa.Table("table1", metadata,
sa.Column('col1', sa.types.Integer,),
)
table2 = sa.Table("table2", metadata,
sa.Column('col1', sa.types.Integer,),
)
table3 = sa.Table("table3", metadata,
sa.Column('col1', sa.types.Integer,),
)
metadata.bind = engine
connection = engine.connect()
trans = connection.begin()
try:
table1.create(bind=connection)
table2.create(bind=connection)
table2.create(bind=connection)
table3.create(bind=connection)
trans.commit()
except:
trans.rollback()

Cheers,
