This mixin provides functionality for the Range Operators
listed in Table 9-44 of the `postgres documentation`__ for Range
Functions and Operators. It is used by all the range types
provided in the ``postgres`` dialect and can likely be used for
any range types you create yourself.
__ http://www.postgresql.org/docs/devel/static/functions-range.html
No extra support is provided for the Range Functions listed in
Table 9-45 of the postgres documentation. For these, the normal
:func:`~sqlalchemy.sql.expression.func` object should be used.
