I'm one of the developers working on the new PostgreSQL website, and while reviewing for outdated information I noticed there's some new books published in 2017 & 2018 that aren't in the Books database. Are there any arguments against including these?
Additionally, I think it'd be a great idea to have more versatile resources provided to people looking to learn PostgreSQL. That seems to be the biggest barrier preventing people from getting started, from conversations I've had at conferences. So I'd like to include a new page under "Documentation" labeled something like "Online Resources".
