I think this fails the basic sanity check: do you need it to still work
when the master is dead. It's reasonable to ask the master to supply a
few gigs of very-recent WAL, but as soon as the word "archive" enters
the conversation, you should be thinking in terms of a different
machine. Or at least a design that easily scales to put the archive on
a different machine.
