Fixed and attached the revised patch.
However, isn't StandbyRequested true (= standby_mode set to on) to enable
warm standby? I'm afraid people set max_wal_senders>0 and hot_standby=on
even on the primary server to make the contents of postgresql.conf identical
on both the primary and the standby for easier configuration. If so, normal
archive recovery (PITR, not the standby recovery) would face the original
problem -- unnecessary WAL accumulation in pg_xlog/. So I'm wonder if
AllowCascadeReplication() is enough.
Please take either this patch or the previous one.
