[GENERAL] PERFORM statement

[Mike Christensen]

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Is the FAQ out of date or was this feature removed?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!
