PostgreSQL 15 Released - What's New

 The long awaited release of the most popular advanced open source database is finally here carrying many bells and whistles. It includes performance improvements on managing workloads in both local and distributed deployments and enchantments that will also make the developers out there happy.



Let's start with the highlight of the release, which arrived on October 13, the introduction of the MERGE statement. It's not just a more convenient way of doing SELECT followed by UPDATE/INSERT, an operation that would be transmitting the selected rows over the network and keeping the rows in-memory on the client side. With MERGE, you now keep the rows in-memory on the server without incurring the network penalty.
