Is there a GoTo ?

[İlyas Derse <ilyasderse@xxxxxxxxx>]

In this function I have to GOTO to a label1, but GOTO keyword is not working, can you please help me in getting the way from which I am able to jump from a particular code to label.

 Thanks...

CREATE OR REPLACE FUNCTION test(i integer) RETURNS integer AS $$
BEGIN
IF i<0 THEN 
RETURN i + 1;
ELSE
  GOTO label1;
END IF
<<label1>>
RETURN null;
END;
$$ LANGUAGE plpgsql;
