After erasing the "less than names" WAL files, we add to tar the remaining

have after 0003B, the more up to date DB you get after restore (since it has
more WAL files indicating more transactions that took place after the backup.
Why bother trying to delete WAL files older than the .backup file? When PostgreSQL is in recovery mode it knows which WAL files are necessary to perform the recovery.
Also, the documentation recommends excluding the pg_xlog directory when performing the base backup. Likely when it comes time to recovery the online WAL files have been archived already, so it is a risk of confusion I am sure.
