I do agree that that's something interesting to document somewhere. But
I don't think any of the current places in the documentation are a good
fit, and it's a topic much more general than the feature we're debating
here. I'm not volunteering, but a good discussion of storage and the
interactions with postgres surely would be a significant improvement to
the postgres docs.
