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. c sp e Zd ZdZ� fdd�Zdd� Zdd� Zdd � Zd d � ZeZ d d � Z e Z dd� Z dd� Z dd� Zdd� Z� ZS )z!RangeOperators.comparator_factoryz-Define comparison operations for range types.c s. |dkrt tj| ��|�S | j�d�|�S dS )z<Boolean expression.
