    * Note: doing "magic srid support" requires constantly going back to the spatial_ref_sys column for information about what srs the srid maps to.  One way to make "magic latlon support" work would be to have a single "islatlon" flag on the geometry object in addition to the srid number, which would be set by setsrid (again, through a lookup to spatial_ref_sys, but just once, instead of every time).
 
- * '''Geodetic Support'''
-  * At the most basic level, geodetic support would enable the database to handle global lat/lon data transparently do a number of issues.  As above, functions like Distance() and Area() would return in metric units even though the base data is in spherical coordinates.  More importantly, the -180/180 wraparound and the poles would be transparently handled by such functions and by the index.  pg_sphere may have some lessons to teach us here.  The trick is to handle spherical coordinates without having to re-write a whole second system.
