Does it matter? pg_standby's source area wouldn't normally be an
"archive" in the real sense of the word, it's just a temporary staging
area between master and slave. (If it were being used as a real
archive, keeping it on the same disk as the live slave seems pretty
foolish anyway, so the case wouldn't arise.)
