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 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 2019-03-11 14:04:45.121 CST [21749] LOG: listening on IPv6 address "::", port 5432 2019-03-11 14:04:45.123 CST [21749] LOG: listening on Unix socket "/tmp/.s.PGSQL.5432" 2019-03-11 14:04:45.135 CST [21749] LOG: redirecting log output to logging collector process 2019-03-11 14:04:45.135 CST [21749] HINT: Future log output will appear in directory "log". stopped waiting pg_ctl: could not start server Examine the log output. ``` 日志提示 ``` [xdb@localhost log]$ cat postgresql-2019-03-11_122129.csv 2019-03-11 12:21:29.233 CST,,,1680,,5c85e249.690,1,,2019-03-11 12:21:29 CST,,0,LOG,00000,"ending log output to stderr",,"Futu 2019-03-11 12:21:29.236 CST,,,1682,,5c85e249.692,1,,2019-03-11 12:21:29 CST,,0,LOG,00000,"database system was interrupted; la 2019-03-11 12:21:29.249 CST,,,1682,,5c85e249.692,2,,2019-03-11 12:21:29 CST,,0,FATAL,42601,"syntax error in file ""recovery.c 2019-03-11 12:21:29.250 CST,,,1680,,5c85e249.690,2,,2019-03-11 12:21:29 CST,,0,LOG,00000,"startup process (PID 1682) exited w 2019-03-11 12:21:29.250 CST,,,1680,,5c85e249.690,3,,2019-03-11 12:21:29 CST,,0,LOG,00000,"aborting startup due to startup pro 2019-03-11 12:21:29.252 CST,,,1680,,5c85e249.690,4,,2019-03-11 12:21:29 CST,,0,LOG,00000,"database system is shut down",,,,,, ``` 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. **参考资料** [Base Backup & Point-in-Time Recovery](http://www.interdb.jp/pg/pgsql10.html)
