Nod.  And if you're at DEBUG5, the log contains so much other crap that
it is unusable for any purposes anyway.

My opinion is that adding these things willy-nilly is not a solution to
any actual problem.  Adding a few additional log lines that are
low-volume at DEBUG1 might be useful, but below that (DEBUG2 etc) it's
not good for anything other than specific development, IMO.  At least
this particular one for streaming replication I think we should not
include.
