It'd prefer if the slave could automatically fetch a new base backup if
it falls behind too far to catch up with the available logs. That way,
old logs don't start piling up on the server if a slave goes offline for
a long time.
The slave could for example run a configurable shell script in that
case, for example. You could then use that to rsync the data directory
from the server (after a pg_start_backup() of course).
