(I'd rather use PgBackRest, but can't due to the fact that the immutable filesystem where we must store backup files doesn't support links. 😞)
Thus, I'm archiving WAL files and taking basebackups.
At some point, when I'm ready to delete the oldest basebackup directory, I'll also of course need to run "pg_archivecleanup /Database/backups/wals mumble".
The .backup file is not in the pg_wal.tar file, so how do I know which .backup file to use?
archive_command = '/usr/local/bin/postgres/wal_archive.sh "%p" "%f"'
$ cd /Database/backups/wals
$ dir *backup

Death to <Redacted>, and butter sauce.
Don't boil me, I'm still alive.
<Redacted> lobster!
