How to call SETOF function?

[Iain Barnett <iainspeed@xxxxxxxxx>]

If I run the following (in either a terminal or the PgAdmin3 Query tool) I get the error:

ERROR: query has no destination for result data

SQL state: 42601

Hint: If you want to discard the results of a SELECT, use PERFORM instead.

Context: PL/pgSQL function "anything_all_udf" line 3 at SQL statement

How am I'm supposed to call the function so that I get the same result as the adhoc query it surrounds?

----

create table anything (

  first serial primary key not null

, second varchar not null

, third timestamp default now() not null

);

insert into anything ( second ) values ( 'row a' );

insert into anything ( second ) values ( 'row b' );

insert into anything ( second ) values ( 'row c' );

CREATE OR REPLACE  FUNCTION anything_all_udf(

) RETURNS setof anything

AS $$ 

BEGIN

select * from anything;

END;

$$ 

LANGUAGE plpgsql;

select * from anything_all_udf( );
