Log message:
    Fix coredump problem in plpgsql's RETURN NEXT.  When a SELECT INTO
    that's selecting into a RECORD variable returns zero rows, make it
    assign an all-nulls row to the RECORD; this is consistent with what
    happens when the SELECT INTO target is not a RECORD.  In support of
    this, tweak the SPI code so that a valid tuple descriptor is returned
    even when a SPI select returns no rows.
