Hi,
I am migrating a project from SA 0.3 to SA 0.4 and the following field/
index produces an error:
sa.Table('resource_path', self.db_metadata,
sa.Column('id', sa.Integer, primary_key =
True),
sa.Column('path', sa.Binary(255), index = True),
mysql_engine='INNODB'
)
The complete error message is:

------------------------
The same table specification works in SA 0.3. Any idea?
