Comment (by strk):

 Now this is funny, I can create a NULL TopoElementArray like this:
 {{{
 SELECT topology.TopoElementArray_agg(e)::TopoElementArray IS NULL from (
   SELECT '{1,1}'::TopoElement WHERE false
 ) as foo(e);
 }}}

 Now I wonder why the "dimensions" constraint only kicks in with a literal
 !
 This is PostgreSQL 9.3.6.
