  * summary:  Geography inconsistent distance behavior from geometry can't
              compare different dimensonality => Geography
              inconsistent distance behavior from geometry
              and geography flag counting flaky

Comment:

 If we are not going to allow this - gives gbox_overlaps: geometries have
 mismatched dimensionality:

 {{{
 SELECT ST_Distance(ST_GeographyFromText('SRID=4326;POINT(-10 50)'),
                         ST_GeographyFromText('SRID=4326;LINESTRING(-10 40
 1,-9 41 1)'));
 }}}

 Then we certainly shouldn't be allowing this which happens to work.

 {{{
 SELECT ST_Distance(ST_GeographyFromText('SRID=4326;POINT(-10 50 1)'),
                         ST_GeographyFromText('SRID=4326;LINESTRINGM(-10 40
 1,-9 41 1)'));
 }}}
