Comment(by pramsey):

 First cut is in at r7894.

 The <-> operator is now a distance operator. It returns the squared
 distance between the centroids of the objects.

 Example getting 10 nearest named points from a names table.
 {{{
   SELECT name,ST_AsText(geom)
   FROM geonames
   ORDER BY geom <-> ST_SetSRID(ST_MakePoint(-90,40),4326)
   LIMIT 10;
 }}}
