The immediate cause of the WAL retension is the archive failure.
PostgreSQL, while archiving is enabled, won't remove a WAL file until
it is successfully archived.

You will see the lines like the following in sergver log if archive
failure happened.

> 2022-03-03 17:15:21.314 JST LOG: archive command failed with exit code 1

If the archive command emitted some error messages, it can be caught
in the server log together. The follwoing error is emitted by the
archive_command "cp %p /archive/%f".

> cp: cannot create regular file '/archive/000000010000000000000001': No such file or directory
