Hmm, in newer versions of rsync --remove-sent-files has been replaced
by --remove-source-files, so I cannot test. Some searching found that
--remove-sent-files will move/delete unfinished files. I would say that
the above cron command is dangerous. To test, comment out the command
and let the archiving run. Postgres will recycle WALs on its own when
they are no longer needed. Or is there is some compelling reason you
want to get rid of WALs?

Aah, so it is just noise.
