: 7.0.3 does not really work in this example (didn't you ever eyeball the
: resulting sort order closely??). 7.1 does not support the example at
: all. The error message from beta4 is not very good, but beta5 says the
: right thing:
:
: ERROR: ORDER BY on a UNION/INTERSECT/EXCEPT result must be on one of the
result columns
:
: Possibly some future release will actually do the right thing with ORDER
: BY of an expression on the output columns, but right now it has to be an
: output column, period.

OK... I tried adding UPPER(last_name) to the result column lists of both
sides of the union and it still gives me the same error.
How can I fix this?
