Should this figure out and use a path to the find command? Unless
postgres sets CWD, is it possible as-is to coerce it into rming some
files you did not intend to have rm'd? I didn't have/spend time
looking at it with a fine toothcomb, but usually calling find and rm
without an explicit path is a Bad Thing(tm).
