+1. This mechanism seems like a solution in search of a problem.
Just lose the whole thing, and instead fix pg_dump to complain if
the target directory isn't empty. That should be sufficient to guard
against accidental mixing of different dumps, and as Heikki says
there's not a good reason to prevent intentional mixing.
