I also tend to agree; it'd be really handy. pg_clearxlogtail (which I
use) makes me nervous despite the restore tests I've done.
If Pg truncated the WAL files before calling archive_command, and would
accept truncated WAL files on restore, that'd be really useful. Failing
that, packaging pg_clearxlogtail so it was kept in sync with the main Pg
code would be a big step.
