 完成

我在linux 启动postgres数据库，返回的内容有中英文混合，所以做了个测试。

结论：

返回信息分为上下两块。

1、postgres打印信息内容

....2020-11-03 17:19:24.800 CST [113539] LOG:  starting HighGo Database 6 Release 6.0.0-64-bit Production
2020-11-03 17:19:24.801 CST [113539] LOG:  listening on IPv4 address "0.0.0.0", port 5866
2020-11-03 17:19:24.801 CST [113539] LOG:  listening on IPv6 address "::", port 5866
2020-11-03 17:19:24.802 CST [113539] LOG:  listening on Unix socket "/tmp/.s.PGSQL.5866"
2020-11-03 17:19:24.827 CST [113539] LOG:  This is a trial edition, validate until 2021-10-10 14:21:05, database will not be able to start up after that time,please apply an official license by that time.
2020-11-03 17:19:24.924 CST [113540] LOG:  database system was shut down at 2020-11-03 17:19:20 CST
2020-11-03 17:19:24.929 CST [113539] LOG:  database system is ready to accept connections

2、os调用命令返回内容

 完成
服务器进程已经启动

 

 这样看的话就很容易理解了。

修改方法：

1、pg打印信息，修改postgresql.conf ，搜索/lc_messages，我们把属性改成中文

#vi postgresql.conf 
#/lc_messages

lc_messages = 'zh_CN.utf8' 

2、修改os字符集，临时生效使用export

export LANG=en_US.UTF-8

3、再次启动

[highgo@baidu data]$ pg_ctl start

这样就和图1完全相反了
