Now to the question.
Once the archive_command starts lying about its success, postgresql deletes

Why does it do this? Can I control it? Can I turn it off?
Because they're no longer needed.
If you want to keep those files, make the archive_command not lie.
Normally posgres will rename the old WAL files that have been archived and are no longer needed,
keeping the number of WAL files constant. In this case, it actually deletes them.
Why is the behaviour different?
