Tutorial documentation bug

Hi,

While reading the tutorial at
http://www.postgresql.org/docs/tutorial/sql-language.htm
I came across a bug.

In Chapter 2, Example 2-9.: "Union, Intersect, Except"
the tutorial states:

-------------- start quote ------------------
Here an example for INTERSECT:

SELECT S.SNO, S.SNAME, S.CITY
    FROM SUPPLIER S
    WHERE S.SNO > 1
    INTERSECT
    SELECT S.SNO, S.SNAME, S.CITY
    FROM SUPPLIER S
    WHERE S.SNO > 2;


gives the result:

 SNO | SNAME |  CITY
-----+-------+--------
  2  | Jones | Paris


The only tuple returned by both parts of the query is the one having
$SNO=2$.

---------------- end quote -------------------

The result is really:

 sno | sname |  city
-----+-------+--------
   3 | Adams | Vienna
   4 | Blake | Rome
(2 rows)


Kind regards,
