The PostgreSQL community tries to keep a list of new features that are added in its feature matrix: https://www.postgresql.org/about/featurematrix/ https://www.postgresql.org/about/featurematrix/ This is not an exhaustive list, but it contains a lot. You would still have to cull information from release notes: https://www.postgresql.org/docs/release/ https://www.postgresql.org/docs/release/ Or looking at the documentation page for a command (e.g. SELECT), or as per other suggestions, reading blogs/articles.
