Ability to cast from geography to geometry

[robe]

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

I've removed the unrelated info from the ticket.
