Hi,

pg_archivecleanup removes unnecessary WAL files from the archive, but not
from pg_xlog directory. So, after failover, those WAL files might
exist in pg_xlog
and be archived again later. Re-archiving of unnecessary WAL files seems odd
to me. To avoid this problem, how about changing pg_archivecleanup so that
it removes WAL files also in pg_xlog or creates .done file in
archive_status when
removing them from the archive?

Regards,
