Yeah, that's about the size of it :-(. Note though that you could
probably work around the problem by pushing the UNION etc. down into a
sub-select:
SELECT * FROM (SELECT ... UNION ...) foo;
At some point we could look at automatically transforming the query in
that way, but I'm not planning to worry about it now.
