hello all!

I want to simulate objects with Postgres and I would like to know if it's
possible to create a type (like address: t_address) and then to create
another type (like customer) with an attribute of type t_address.

And I have a second question:
Can I make a "reference" to an object of an existing type?!

These are features provided by the SQL3 standar, I want to know if it's
possible to implement it with Postgres.

Can somebody help to me?!

Thank you in advance,

//Ingrith Correa :)
