set return function is returning a single record, multiple times, how can i get all the records in the table( description inside )

Hi

Please spare some time to provide a solution for the described
problem :

I am using set returning functions to return all the records from a
table named pss ,

But what I am getting is the first record is returned as many times ,
the number of records present in the rank_master:

I am giving a detailed description below please check it out

1) The following query creates pss table:

create table pss( name varchar(20), num integer, phno integer );

2) insert three records in to pss :

insert into pss values('penchal',1,420);

insert into pss values('joe',2,421);

insert into pss values('ali',3,422);

3) create an user defines type of variable named structrankmaster2 (
something like a structure to hold a record ) :

create type Structrankmaster2 as (name varchar(20), num integer, phno
integer);

4) The following is the function that retrieves the records from pss :

CREATE or replace FUNCTION ftoc9() RETURNS setof structrankmaster2
LANGUAGE 'plpgsql'

AS' DECLARE

rowdata pss%rowtype;

BEGIN for i in 1..3 loop

select * into rowdata from pss ;

return next rowdata ;

end loop;

return;

end';

5) now call the function from command prompt:

Select * from ftoc9();

6) the following is the output that I am getting ( i.e the first row
repeated 3 times ) :

name | num | phno

---------+-----+------

penchal | 1 | 420

penchal | 1 | 420

penchal | 1 | 420

(3 rows)

7) what exactly I should be getting is :

name | num | phno

---------+-----+------

penchal | 1 | 420

joe | 2 | 421

penchal | 3 | 422

(3 rows)

Please provide a solution for this so that I can get

name | num | phno

---------+-----+------

penchal | 1 | 420

joe | 2 | 421

penchal | 3 | 422

(3 rows)

Thanks & regards
