我按照说明操作 here ，此处显示了我的参数组更改摘要:
我重新启动了实例和一切，我得到了这个新的日志文件:
在 error/postgres.log 里面，我只有这个:
2018-03-13 12:39:38 UTC::@:[28236]:WARNING: unrecognized configuration parameter "rds.logical_replication"
2018-03-13 12:39:38 UTC::@:[28236]:LOG: redirecting log output to logging collector process

2018-03-13 14:13:53 UTC::@:[14981]:HINT: Future log output will appear in directory "/rdsdbdata/log/error".
----------------------- END OF LOG ----------------------
一个令人担忧的事情是，我从未收到过这条消息，正如文档中所说的，在应用新更改后我应该收到这条消息:
2013-11-05 16:48:56 UTC::@:[2952]:LOG: received SIGHUP, reloading configuration files
2013-11-05 16:48:56 UTC::@:[2952]:LOG: parameter "log_min_duration_statement" changed to "1"
知道我做错了什么吗？

与下面的正确答案相同，我得到了 RDS 支持的回复并得到了这个:
I would like to let you know that I can see the Log files getting generated for your instance after applying the parameter group changes. Moreover I can also see the size of these log files getting larger. The log files that are getting generated after applying the modification for parameter group and reboot(attached parameter group at 2018-03-13 12:35:58 UTC and reboot at 2018-03-13 12:39:33 UTC), are as follows:

最佳答案
文档似乎有些不一致/已过时。当我今天早上更改参数组并重新启动时，我得到了同样内容相同的奇怪错误/postgres.log 文件。
不知道这是否适合您，但对我来说这只是以愚蠢的顺序对日志进行排序。我刷新，按“最后写入(降序)”排序，弹出了实际最新的日志。
