PERFORM statement

[Mike Christensen <mike@xxxxxxxxxxxxx>]

I was reading about Postgres stored procs in the FAQ:

https://wiki.postgresql.org/wiki/FAQ#Does_PostgreSQL_have_stored_procedures.3F

It claims that an alternative syntax to:

SELECT theNameOfTheFunction(arg1, arg2);

Is:

PERFORM theNameOfTheFunction(arg1, arg2);

However, when I try the following:

CREATE TABLE app_for_leave

(

  sno integer NOT NULL,

  eid integer,

  ename varchar(20),

  sd date,

  ed date,

  sid integer,

  status boolean DEFAULT false,

  CONSTRAINT pk_snoa PRIMARY KEY (sno)

);

CREATE FUNCTION MyInsert(_sno integer, _eid integer, _sd date, _ed date, _sid integer, _status boolean)

  RETURNS void AS

  $BODY$

      BEGIN

        INSERT INTO app_for_leave(sno, eid, sd, ed, sid, status)

        VALUES(_sno, _eid, _sd, _ed, _sid, _status);

      END;

  $BODY$

  LANGUAGE 'plpgsql' VOLATILE

  COST 100;

PERFORM MyInsert(1,101,'2013-04-04','2013-04-04',2,'f' );

I get the error:

ERROR: syntax error at or near "PERFORM"

SQL state: 42601

Character: 1

Is the FAQ out of date or was this feature removed?  I'm using 9.2.1.  Thanks!
