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,

- Mikael -

P.S. I am not on the pgsql-docs mailing list, so I won't
see any replies sent there.
