In a quick glance this code seems close to completely brain dead :-(
For one thing, why isn't it making separate determinations about whether
the left and right inputs of the UNION (resp INTERSECT or EXCEPT)
operator need to be parenthesized?  After that maybe we could figure out
what the individual decisions need to be.
