Taken from the postgresql manual
(http://www.postgresql.org/docs/view.php?version=7.3&idoc=0&file=sql-select.html#SQL-UNION):
ORDER BY and LIMIT can be attached to a sub-expression if it is enclosed in
parentheses. Without parentheses, these clauses will be taken to apply to the
result of the UNION, not to its right-hand input expression.
Regards.
