Comment:
The geography described by those points is not invalid. The documentation
says that st_isvalid only works on geometry (not geography).
http://postgis.refractions.net/docs/ST_IsValid.html As such it won't
correctly validate the geography that I was using to demonstrate this
problem. This is a polygon that wraps around the north pole which isn't
possible as a geometry object in postgis but should be possible as
geography.
