Seems a mistake in tutorial-7.2-A4.pdf file - Mailing list pgsql-docs

Hi,

I'm learning psql reading tutorial-7.2-A4.pdf file and doing
exercise from this document.
It seems there is a mistake in it.
On pages 14-15 of mentioned document it's written:

...<page 14>
The new declaration of the tables would look like this:

CREATE TABLE cities (
name varchar(80) primary key,
location point
);
                                                          14
...<page 15>
                                Chapter 3. Advanced Features

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

Now try inserting an invalid record:
...


IMHO line `city varchar(80) references weather,'
must be   `city varchar(80) references cities,'.

Best regards,
Serge.
