I actually think we should *always* use the new code and not add a separate wal_level=minimal branch. Maintaining this twice just isn't worth the effort. minimal is used *far* less these days.
I wouldn't go that far. Doing the wal_level=minimal optimization should be pretty straightforward. Note that it would be implemented more like CREATE INDEX et al with wal_level=minimal, not the way CREATE DATABASE currently works. It would not involve any extra checkpoints.
