Top 3 features in Postgres 17

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.
