This changes <application>pg_basebackup</>'s
- <option>-X</>/<option>--xlog-method</> default to <literal>stream</>.
+ <option>-X</>/<option>--wal-method</> default to <literal>stream</>.
An option value <literal>none</> has been added to reproduce the old
behavior. The <application>pg_basebackup</> option <option>-x</>
has been removed (instead, use <literal>-X fetch</>).
