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
recovery_target_time='2019-3-11 14:40:00'
如按上述设置,则会出现错误
[xdb@localhost testdb]$ pg_ctl start

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
testdb=# show datestyle;
DateStyle
-----------
ISO, MDY
(1 row)
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.
