I was surprised to come across new "Postgres Advanced" options and a pricing calculator on the add-on page today: https://elements.heroku.com/addons/heroku-postgresql

The article is dated October 2025, but I don't recall ever hearing about this before, and it doesn't look like anything has ever been posted on HN.

The separation of storage and compute is new for Heroku, though they are not the first to do so. So far it seems like there's still only fixed combinations of vCPU and RAM, and that the price of each "no storage included" instance is more than the equivalent storage-included "Classic" instance size.
