Another question about composite types

  Hi, I need to create a table like:

  CREATE TYPE t_salary AS (

    Value numeric(10,2),

    Validity date

  );

  CREATE TABLE employee (

     id int,

     name varchar(30),

     salary t_salary[]

  );

  That is, I need an array of composite type and searching on google I found that is impossible to do it! Is it really impossible? Anyone have do it ?

 Thanks!
