我正在Linux两个节点上配置postgres 9.6（1个主节点，另一个是从节点） https://www.howtoforge.com/tutorial/how-to-install-and-configure-master-slave-replication-with-postgresql-96-on-centos-7/

按照上面的注释进行了所有配置，从注释进行配置后，主节点正在运行

但是当我启动从属节点并在从属端的日志中看到以下消息时，给出了从属配置表格的注释：

< 2020-03-17 01:12:07.408 +04 > LOG:  database system was interrupted while in recovery at log time 2020-03-17 00:37:30 +04
< 2020-03-17 01:12:07.408 +04 > HINT:  If this has occurred more than once some data might be corrupted and you might need to choose an earlier recovery target.

< 2020-03-17 01:12:07.422 +04 > FATAL:  hot standby is not possible because wal_level was not set to "replica" or higher on the master server
< 2020-03-17 01:12:07.422 +04 > HINT:  Either set wal_level to "replica" on the master,or turn off hot_standby here.

使用postgres很新，想知道我是否错过了某些内容，或者我注意到的是缺少了某些内容。

有一些Google，但是很遗憾找不到任何东西。
