Question

Postgres Replication在Postgresql 9.5版中正常工作。创建具有10gb数据的数据库模板，然后从属服务器停止时。它的Postgres服务现在还没有启动。您能建议如何重新配置复制吗？我尝试重新安装并执行相同的复制步骤，但是从主服务器复制数据文件夹（conf文件除外）后，该服务未运行。这些是我遵循的步骤：在Master中：-

*C:\Programfiles\PostgreSql\9.5\data\postgresql.conf
Modifications:
listen_addresses = '*'
wal_level = hot_standby
max_wal_senders = 1
wal_keep_segments = 5
* C:\Programfiles\PostgreSql\9.5\data\pg_hba.conf
    Add:                                
host    replication     postgres        x.x.x.x/32         trust

在奴隶中：

'*C:\Programfiles\PostgreSql\9.5\data\postgresql.conf'
    'hot_standby = on'

然后在路径

下创建一个名为recovery.conf的文件。

‘C:\Programfiles\PostgreSql\9.5\data\’  and add:'
'standby_mode = 'on'
'primary_conninfo = 'host=x.x.x.x port=5432  user=postgres'  
'password=*****''
'trigger_file = 'E:\replication\trigger.txt'

在大师中：启动Postgresql服务。打开Sql Shell（psql）键入命令

select pg_start_backup('base backup');

然后将数据目录中的所有内容（不包括postmaster.pid）和所有配置文件（.conf）复制到从系统的数据目录中现在输入命令

select pg_stop_backup();

请提出一种恢复该复制的方法。

这是错误日志
