INSERT INTO employee (emp_salary)  VALUES ((1000.00, '(2006/10/10, 2006/12/10)'));


BTW: are you sure you don't want to use foreign keys instead? Something 
like:

CREATE TABLE salaries (  id SERIAL PRIMARY KEY,  salary numeric(10,2) NOT NULL,  t_date t_time NOT NULL
);

CREATE TABLE employee (  employee_id SERIAL PRIMARY KEY,  name TEXT NOT NULL,  salary INT NOT NULL REFERENCES
salaries(id)
);

I am thinking that with the salary type here you are thinking of your 
salary table defined above?
If so and you want them in a separate table to record salary histories 
then you want to create a foreign key to link them.

You would end up with -

CREATE TABLE employee (
  employee_id int PRIMARY KEY,
  name varchar(30)

);

CREATE TABLE salary (
   emp_id int REFERENCES employee(employee_id) ON DELETE CASCADE,
   salary numeric(10,2),
   t_date t_time

);

then -
INSERT INTO salary VALUES (1, 1000.00, '(2006/10/10, 2006/12/10)');


Otherwise you will want to change the CREATE TABLE salary... to CREATE 
TYPE salary...

Probably as
CREATE TYPE salary AS(   salary numeric(10,2),   a date,   b date
);

You can then
INSERT INTO employee VALUES
(1,'Hard Worker','(1000.00, 2006/10/10, 2006/12/10)');

'(01/01/2000, 01/01/2000)')));

  Thanks, It works! I have tried:

insert into employee (c, nome, sal) values(1, 'emp name', '(1, (01/01/2000,
01/01/2000))' );
 And it doesn't work!
