The problem is how much WAL is stored on (any) node. Currently that is
wal_keep_segments, which doesn't work very well, but I've seen no better

What about allowing the master to read and send WAL from the archive?
Regards,
Then you have to deal with telling the archive how long it needs to keep
WAL segments because the master might ask for them back. If the archive
is remote from the master then you have some extra network copying going
on. It would be better to let the slave being reconfigured to read the
missing WAL from the archive.
