Problem with Trigger in Postgres DB

I need to creata a trigger:

   
       
        CREATE OR REPLACE TRIGGER IS_PI_AFTER_UPDATE
        AFTER UPDATE
        ON USERS
        FOR EACH ROW
        DECLARE
        BEGIN
            IF (:OLD.IS_PI != :NEW.IS_PI) THEN
                  IF(:NEW.IS_PI = ‘true’) THEN
                     INSERT INTO PI_DELEGATES (PI_USER_ID, DELEGATE_USER_ID) VALUES (:NEW.USER_ID, :NEW.USER_ID);
                  ELSE
                     DELETE FROM PI_DELEGATES  WHERE PI_USER_ID = :NEW.USER_ID AND DELEGATE_USER_ID = :NEW.USER_ID;
                  END IF;   
            END IF;
        END
/
                    
   


I tried various options, but it always complains about missing ; at the end. Can you please identify the problem.
This is the output:

Does it help to add a “;” at the end of your SQL before the /?
