Hi,
patch approved, just one minor comment.

I would use a different function that POLYGON here. Otherwise people 
will get surprised that such a limited-application function is needed. 
You can provoke that crash using

SELECT * FROM t1 GROUP BY
(SELECT a FROM t2 LIMIT 1 FOR UPDATE) + t1.a;

otherwise, great patch.
