group by and count(*) behaviour in 8.3 - Mailing list pgsql-general

I am using this query in 8.3beta4 (compiled from source) in MacOS X 10.5.1

SELECT webName,count(*) FROM contenitore NATURAL JOIN cartellino WHERE
contenitore.tipo='e' GROUP BY webName;

this is the result
                       webName                      | count
--------------------------------------------------+-------
   test palermo                                     | 36679

   Herbarium Universitatis Aeserniae - IS           | 36679

   Segnalazioni Siena                               | 36679
   Herbarium Aquilanum - AQUI                       | 36679
(10 rows)

but 36679 is the total number of row of the table.
The same query in 8.1.4 retrieves the aspected result (the number of
elements for each webName).

Is this a bug or a change in the semantic of SQL?

thank you
Edoardo
