Rob Conery's A Curious Moon (https://bigmachine.io/products/a-curious-moon/ https://bigmachine.io/products/a-curious-moon/) is an interesting read for a PostgreSQL book. I wouldn't say it tries to be an advanced book by design, but I learned a lot of modern SQL from it. I think the number of people needing truly advanced books is small whereas a lot of people need to jump from beginners to intermediate, or intermediate to advanced.
