One more point related to logical replication features:

Add SQL functions to monitor the directory contents of replication
slots (Bharath Rupireddy)
Specifically, the functions are pg_ls_logicalsnapdir(),
pg_ls_logicalmapdir(), and pg_ls_replslotdir(). They can be run by
members of the predefined pg_monitor role.

This feature is currently under the section "Streaming Replication and
Recovery". Shouldn't it be under "Logical Replication"? The function
names themselves seem to indicate that they are used for logical
replication contents. I think the replication slot-related function
would fall under both categories but overall it seems to belong to the
"Logical Replication" section.
