Postgres Professional, a developer of data management products, has released version 17.5.1 of its Postgres Pro Enterprise DBMS. The system now supports embedded analytics, offers automated database tuning, introduces a new backup technology, and much more .

Postgres Professional introduces a scheduled update to the Postgres Pro Enterprise Manager (PPEM) platform—a comprehensive administration and maintenance solution for Postgres Pro databases. The new release includes features for real-time infrastructure monitoring, performance bottleneck detection, and management of Patroni-based high-availability clusters.

Postgres Professional has issued updates for Postgres Pro Standard. Versions 13.21.1, 14.18.1, 15.13.1, 16.9.1 and 17.5.1 are now available for download and upgrade from the official repository. Below is an overview of the fixes and enhancements that have been updated or newly introduced for 17.5.1 users.
