Comment(by robe):

 Iffy sounds like an iffy "no way". Would this option be better than doing


 {{{
 SELECT ... ORDER BY a.geom_4326 <-> b.geom_4326
 }}}

 If not then I guess not worth the effort. The never return exact results
 doesn't bother me so much since for most cases, people use this as a first
 hope anyway and not the final.  Anyway probably something to vote on
 rather than do blindly.
