PostgreSQL 18 has been released, featuring significant performance improvements through a new asynchronous I/O subsystem, enhanced query execution capabilities, and easier major-version upgrades. The release also introduces new features such as virtual generated columns, OAuth 2.0 authentication support, and improved statistical handling during upgrades, solidifying PostgreSQL's position as a leading open source database solution.

Greenmask is an open-source utility for logical database backup, anonymization, and synthetic data generation that operates without requiring changes to the existing database schema. It offers advanced features like database subset systems, deterministic transformers, and dynamic parameters, while ensuring compatibility with PostgreSQL utilities for seamless integration. The tool is designed to be stateless, cross-platform, and extensible, making it ideal for various data management scenarios.

PostgreSQL 18 Beta 1 has been released, offering a preview of new features aimed at improving performance and usability, including an asynchronous I/O subsystem, enhanced query optimization, and better upgrade tools. The PostgreSQL community is encouraged to test the beta version to help identify bugs and contribute feedback before the final release expected later in 2025. Full details and documentation can be found in the release notes linked in the announcement.
