Hi!
I am using SQLAlchemy 0.9.8 and py-postgresql 1.1.0.
When I used the Column name without parentheses, it works perfectly.
But, the following code receives KeyError.
from sqlalchemy import create_engine, Table, Column, Integer, Float, String,
MetaData
engine =
create_engine("postgresql+pypostgresql://tester:xxxxx@localhost/test_db")
engine.execute("DROP TABLE IF EXISTS test_table")
metadata = MetaData()
users = Table('test_table', metadata,
Column('E(1)', String),
Column('E(2)', Float),
Column('E[3]', Integer)
)
metadata.create_all(engine)
ins = users.insert().values(
{'E(1)': "FOO", 'E(2)': 1000.0, 'E[3]': 5})
conn = engine.connect()
result = conn.execute(ins)
result.close()
The error is as follows
Traceback (most recent call last):

Thank you.
