I disabled it because I didn't have time to fix it properly when it got
broken by the 7.1 rewrite of UNION/INTERSECT/EXCEPT. I've been waiting
to see whether anyone notices that it's gone ;-). So far the demand for
it has been invisible, so it hasn't gotten fixed. On the other hand
I'm not quite convinced that it never will get fixed, so I haven't
applied the coup de grace.
