Log message:
    Arrange to give error when a SetOp member statement refers to a variable
    of the containing query (which really can only happen in a rule context).
    Per example from Brandon Craig Rhodes.  Also, make the error message
    more specific for the similar case with sub-select in FROM.  The revised
    coding should be easier to adapt to SQL99's LATERAL(), when we get around
    to supporting that.
