Hmmm ... the crash is certainly UnGood, but is there any reason we
should accept this query rather than generating an error?  I don't
think it's legal vanilla SQL --- the argument of count() should be
either "*" or a scalar expression per the spec.  I don't know what
it means for the argument of count() to be "foo.*".
