I take it you are using 6.4, because 6.5 generates different failure
messages. But it's not any less broken :-(. The rewriter seems to have
a bunch of bugs associated with aggregate functions in HAVING clauses of
sub-selects. Or maybe it's just several manifestations of the same bug.
I have notes about this problem but do not understand it well enough to
fix it. Perhaps Jan has a clue about it...
