Comment(by robe):

 I should add, I'm okay with touching the postgis_typmod_dims even in
 micro. Now I am relooking at what you are saying.  THAT IS A BUG, and
 would probably significantly improve the performance of the view  if we
 changed it (to not assume 2).  The constraint should only kick in if
 absolutely postgis_typmod_dims is known to return no value, as it stands
 it's probably kicking in for most any table (a 2D which I think is a real
 performance killer)
