Обсуждение: Trouble with composite types

Hello,
I don't know why this message is not going through!

I have the following types:
create type street_type as
(
street_number   smallint,
street_name     text,
apt_number      smallint
);

create type address_type as
(
street          street_type,
city            text,
state           char(2),
zip_code        char(5)
);

When I enter that into the command prompt, I the following message:
ERROR:  Attribute "street" has composite type street_type

Why is it giving me error message for something I know is true?  Also, how
do I add a member function to a type?
Thanks,
Yasir
