Creating a new type - Mailing list pgsql-interfaces

  Hi all,

  I have to create a new composed data type to use in almost all tables of my database. Something like:

  CREATE TYPE time_interval (

    Tbegin date,

    Tend date

   )

  And when use this new type in my tables! So, I have to be able to get the table_name or table_id that the type is in. For exemple:

  CREATE TABLE employee (

    Emp_id int,

    Emp_name varchar(30),

    Emp_time time_interval

  )

  So, when I execute an INSERT operation on this table, the functions that deals with this type need the id or name of the table that the data was inserted!
