Comment (by robe):

 ST_MakeValid does not always produce useful output (or at least useful to
 the user, for example it could turn a polygon into a linestring if it
 can't make a valid polygon wihout loosing points) all the time and as a
 general rule. None of our output functions try to make anything valid.
 That's the user's responsibility.  So I think just checking correctness
 and throwing an error if you think it's unacceptable to output, or just a
 warning notice is good enough.
