Date 1973/06/03 Conversion Problem in 7.3.4 and 7.3.2.

Hi to all,

I have a problem storing 1973/06/03 date.

If I send this statement

    select to_date('03/06/1973','dd/mm/yyyy');

in the psql interface I obtain

 to_date
------------
 1973-06-02

I test this statement with Postgres 7.3.2 and 7.3.4 packaged withMandrake 9.1
and Mandrake 9.2RC1 and obtain the same result.

Can anyone help me?
