My mistake --- if you feel like making it so, go to it.

I think the combination of #ifdef and GUC variable is appropriate.
Just because you want to debug something doesn't necessarily mean you
want the log messages on full strength every instant, especially for
high-volume messages such as the WAL ones. You might for instance want
to log just one backend's WAL activity.
