That's where I am unsure. Is the initdb-safe and backup advantages
enough to start to migrate those out to data/? I need to hear
comments on that.
One new idea is to move the config files into data/etc. That makes it
clear which are config files, and makes backup a little easier. It
would make -C more logical because you are not moving a clear directory.
