This appears to be fixed already in current sources --- the problem
is the lack of parentheses around the arms of the UNION. There's
a difference between
SELECT foo UNION SELECT bar ORDER BY baz;
and
SELECT foo UNION (SELECT bar ORDER BY baz);
and the rule dumper was not being careful about it :-(
I'll see about backpatching this change for 7.2.2.
