It is OK for me to omit the description, but there is a note - recovery_target_lsn
would be set with certain LSN.

Yeah, e.g., no need to break lines in the tag.

I expected like;

```
Note, the configuration setting <literal>port</literal> in this file is
effectively ignored while running <application>pg_createsubscriber</application>
as it always specifies the target listening port on the <application>pg_ctl</application>
command-line.
```
