You could just send SQL comments:
-- opwin.py: committing step signoff
One advantage of this is that you can merge the comments with actual
commands, thus not incurring even a network round-trip time for them.
If you do send it separately, it will act like an empty query string.
People tend not to think of this because psql strips -- comments before
sending commands. But I believe all the lower-level libraries will pass
them through. (If you need to pass loggable comments through psql, I
think the /* ... */ form will work.)
