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. - Andres -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
