Comment (by kneufeld):

 Your proposed function does seem to solve the problem, but we would need
 to add a textual overload for every function that also has a geography
 overload.

 ie. this also currently breaks.
 SELECT ST_AsText('POINT(1 3)');

 This means that geography would never benefit from the unknown->text
 autocast (Not that it's a big deal, cuz I too am against autocasts
 anyway).  Additionally, whenever a new geography function was added,
 developers would need to remember to add the textual overide to point to
 the geometry method, avoiding ambiguity.

 You are right. Not having these functions would likely be a breaking
 change for many applications.

 ... or we skip a 1.5 release and go straight to 2.0 where a breaking
 change is almost expected :)
