Comment (by mcayland):

 Since the geography type will require 8.3 minimum for geography support,
 then lets just add the costs directly into the .sql file. I agree that we
 should start by simply adding costs to the functions within any indexable
 ST_* functions, perhaps a cost of 100 to the more expensive function and
 then do some testing to see what happens there.


 ATB,

 Mark.
