I have the following function

integer AS
$body$
DECLARE
   vDATA integer;
BEGIN
COMMIT;
END;
$body$
LANGUAGE 'plpgsql' STABLE CALLED ON NULL INPUT SECURITY INVOKER;

When  I execute i have the error

ERROR:  SPI_execute_plan failed executing query "COMMIT":

I saw at Internet this bug was already reported.
