Postgres 17 is an upcoming release that improves both developer experience and performance. The new MERGE command with RETURNING support allows developers to handle conditional data modifications in a single step, simplifying complex workflows. Enhanced JSON functions enable more straightforward ways to work with semi-structured data, while improved performance features include optimized parallel query processing, vacuum operations, and B-tree index performance. Contributions from Neon engineers also enhanced the Postgres 17 release, including new options for performance tuning, support for parallel builds of BRIN indexes, and improvements in libpq/psql. The upcoming release is planned to be supported by Neon as soon as it's GA.
