Insert into when the type is an other table

Hi,

I created a Tables : Create Table address (contry varchar(20), city varchar(20), zip_code integer),

Create Table person (Name varchar(20), addr address);

I would know how I can Insert Values in person table.

note that Postgres add each created table in pg_types catalog table. so, each table is considered as a data type. is this right?

thanks for your help,

Mourad
