New description:

 Perhaps I missed this -- but how does one CAST from geography to geometry
 without going thru ST_AsText

 I can do this  geography(somegeometry)

 but no equivalent geometry(somegeography)

 and when I do this:  a.the_geog::geometry
 I get this:
 cannot cast type geography to geometry

Comment (by pramsey):

 I've removed the unrelated info from the ticket.
