Don't see any need to add that either (s/archving/archiving/, btw).

Having the same wording for the WAL receiver and the WAL sender could
be confusing when it comes to a cascading standby node, particularly
if log_line_prefix does not include the process PID.

Anyway, those two ones are going to make the logs much more noisy, no?
The same could be said about XLogFileRead(), joining the point of
Nathan's upthread.  So I cannot get excited by this change.
