Rows that contain named row types
The following statement shows you how to insert a row
into the employee table in Create the student table.:
INSERT INTO employee
VALUES ('Poole, John',
ROW('402 High St', 'Willits', 'CA',
ROW(69055,1450))::address_t, 35000 );
Because the address column of the employee table is a named ROW type, you must use a cast operator and the name of the ROW type (address_t) to insert a value of type address_t.
