Cause the format of BC timestamptz output to be 'datetime zone BC' rather
than 'datetime BC zone', because the former is accepted by the timestamptzinput converter while the latter may not be depending on spacing. Thisis not a loss of compatibility w.r.t. 7.4 and before, because until veryrecently there was never a case where we'd output both zone and 'BC'.
