I've only just started looking at this.

In doc/src/sgml/config.sgml:

Note that in addition to these parameters,
<xref linkend="guc-wal-level"> must be set appropriately on the master
server, and may also want to enable WAL archiving as
well (see <xref linkend="runtime-config-wal-archiving">).

s/and may also/and you may also/


In doc/src/sgml/high-availability.sgml:

s/effected/affected/

Also: "i.e., set max_wal_senders, hot_standby and authentication option"

Doesn't sound right.  Perhaps something like "... and configure
host-based authentication"


In src/backend/postmaster/postmaster.c:

(errmsg("terminating walsender all processes to force cascaded"
        "standby(s) to update timeline and reconnect")));

s/walsender all/all walsender/
