Comment (by robe):

 Though this I would consider a bug (at least an error in the error
 message).  Gives error
 ERROR:  gbox_overlaps: geometries have mismatched dimensionality

 even though they are the same dimension.  If we are not going to allow
 these functions to be used with higher dimensions we should change this
 error message.


 {{{
         SELECT ST_DWithin(geography(foo1.the_geom),
 geography(foo2.the_geom), 100), ST_AsEWKT(foo1.the_geom) As ref1_geom,
