[Postgres] Driver does not support theBIT type

[Former user]

Autoloading a Postgres 8.1 table does not work if it contains a column of type BIT since there is no mapping forseen to deal with BIT types.

[Former user]

Which type from sqlachemy.type BIT type from Postgres should be associated?

reflection has been modified such that coltypes which arent defined produce a warning and are implemented in the reflected Table with NullType.
