That's not the case he was complaining about for 7.4 though, it was this
case I think (done on my 7.5 system, but...):

sszabo=# select timestamp '2003-12-11 23:59:59.9999999';
       timestamp
------------------------
 2003-12-11 23:59:60.00
(1 row)

sszabo=# select version();
                                                  version
------------------------------------------------------------------------------------------------------------
