Thanks for the reply. Then, my question becomes as follows: Is there a way for basic PostgreSQL users (as me) benefit from this (yet)? I don't want to dive into any codes :)
Yeah, I think this is all under the hood, so in future releases, Postgres should perform even better for you ;)
It's a framework for future functionality. End-users won't be touching it for some time I expect. The best thing about psql is their careful, iterative engineering.
