bug in tutorial docs

Just in case no one else has found it, in the tutorial docs on page
file:/usr/share/doc/packages/postgresql/html/tutorial-fk.html says:

 >>>
CREATE TABLE weather (
         city            varchar(80) references weather,
         temp_lo         int,
         temp_hi         int,
         prcp            real,
         date            date
);
<<<

and talks about the foreign key insert error.  But that did not work when I
tried it.  I believe the doc should say:

 >>>
CREATE TABLE weather (
         city            varchar(80) references cities,
         temp_lo         int,
         temp_hi         int,
         prcp            real,
         date            date
);
<<<

The difference is the table referenced, cities not weather.  That does allow
the example to work.
