This is not a bug. Use pgsql-general ML instead.

Master and slave are in the same host?

... if master and slave aren't in the same host, restore_command must
grab archives directly from master (or archive directly in slave or
even in another host) such as:
restore_command = 'scp
postgres@myhost:/var/lib/pgsql/11/data/pg_log_archive/%f %p'
In this case, user postgres in myhost must access master without password.
