"""
    Creates a filter which matches suitable right siblings for ``node``,
    where insertion should maintain ordering according to the list of
    fields in ``order_insertion_by``.
    For example, given an ``order_insertion_by`` of
    ``['field1', 'field2', 'field3']``, the resulting filter should
    correspond to the following SQL::
       field1 > %s
       OR (field1 = %s AND field2 > %s)
       OR (field1 = %s AND field2 = %s AND field3 > %s)
