I'm not opposed to this idea. However, I would like to point out that
1) "replication" is mentioned for _replica_ which can introduce some confusion
if we add "logical replication". Maybe it is a good idea to change the sentence
below from "replication" to "physical replication".

2) There is no link to the sentence above. If you add a link to the logical
replication section, I would suggest to add a link to the other cases (WAL
archiving, physical replication) too.
3) If we are using "logical replication", should we mention "logical decoding"?
The Logical Replication chapter mentions the use of logical decoding in the
Architecture section.

I don't think such note should be added. If the DBA doesn't know how to setup
logical replication, it should read the Logical Replication chapter.
