PostgreSQL时间点恢复不工作

我们将2台PostgreSQL服务器设置为主从服务器

我想测试下面的场景

我在master上进行了一次基本备份，然后删除了一个表，并使用命令

select pg_switch_xlog（）切换了xlog文件。然后我阻止了主人。将从属服务器升级为主服务器，并删除了另一个表和交换的日志文件

现在，我已经在一台新服务器上恢复了这两台服务器的基本备份和wal文件，并使用恢复时间来测试PITR。我能够恢复到没有从旧主控中删除任何表或删除1个表的时间。但我无法恢复到从新主控中删除表时的某个时间点

下面是同一系统的日志输出

以下是
recovery.conf
文件的内容：

restore_command = 'cp /var/lib/pgsql/pg_log_archive/%f %p'
recovery_target_time = '2018-08-06 14:20:00.0'
recovery_target_inclusive = 'true'
recovery_target_action = 'promote'

我在这里做错了什么？
恢复不会继续到时间线6，因为您没有添加

recovery_target_timeline = 'latest'

到
recovery.conf
。正如上面所说：

默认情况下，恢复时间与进行基本备份时的时间相同

到目前为止，我正在recovery.conf中使用restore_命令、recovery_target_time、recovery_target_inclusive、recovery_target_action。现在我正在添加恢复目标时间表。现在时间点恢复是否完美？我应该这么说。你能自己编辑你的问题来添加正确的信息吗？
