???Varchar()

I have listened that through new Postgresql 7.2.2 version there is also
the capability of declaring a varchar type without declaring the maximum
number of storage e.g. create table A(att0 varchar(16)). Is is true?If
it's how is declared beacuse i can't manage it. Specifically i can't
declare create table A(att0 varchar()). Does anyone have any idea about
the subject.Thanks you !
