PostgreSQL DBA(29) - Backup&Recovery#2(日期格式导致的错误)

由于日期格式的不同,PostgreSQL在执行恢复读取recovery.conf的时候会出现问题. 
错误信息 
在recovery.conf文件,recovery_target_time的设置

1.  
2. recovery_target_time='2019-3-11 14:40:00'
3.  

如按上述设置,则会出现错误

2. [xdb@localhost testdb]$ pg_ctl start
3. waiting for server to start....2019-03-11 14:04:45.121 CST [21749] LOG: listening on IPv4 address "0.0.0.0", port 5432

在recovery.conf文件的第3行有语法错误,猜测是日期格式问题

日期格式

1.  
2. testdb=# show datestyle;
3. DateStyle
4. -----------
5. ISO, MDY
6. (1 row)
7.  

PG日期格式为月-日-年,recovery.conf文件的日期调整为该格式即可解决上述问题.
