Comment (by pramsey):
Change the docs. <-> will only return sphere distance, it is required to
be that way to harmonize the way the key test in hte index calculates
distance with how the "exact" operator tests. <-> should only be used for
ordering, not measuring, if you want a distance, use ST_Distance, that's
what the docs should say
