We leave that up to the DBA to clean out one way or another. We provide
restartpoint_command and the %r option in restore_command to help with that.
Surely we don't expect DBAs to delete old files in pg_xlog? I agree with
Simon here, I think it would be better to not provide -1 as an option
here. At least you better document well that you should only do that
temporarily or you will eventually run out of disk space.
