Comment (by nicklas):

 That the point disapears comes from the optimization of removing identical
 points.
 From the discussion in the github thread, do you agree this is correct?

 But I do not remember why we don't remove the hole when all the points are
 the same.
 I might recall we had some discussion about it, but I am not sure. The
 alternative would be to:

 "If we don't have at least 3 different points in a hola after reducing
 precision we remove the hole".

 What talks against that solution is that it would put an overhead for all
 holes.
 I see ST_Makevalid can do that job as a postprocessing. I guess that is
 what we thought.
