AXDB 18.4.1 (2026-05-20)

AXDB is a solution that includes PostgreSQL server and the collection of tools from PostgreSQL community. These tools are tested to work together and serve to assist you in deploying and managing PostgreSQL.

The aim of AXDB is to address the operational issues like High-Availability, Disaster Recovery, Security, Observability, Spatial data handling, Performance and Scalability, and others that enterprises are facing.

This release of AXDB is based on AXDB Server for PostgreSQL 18.4 - a binary compatible, drop in replacement of PostgreSQL Community 18.4.

This release includes pg_tde 2.2.0 for Transparent Data Encryption and more. See the full component list below for details.

Note

Starting with this release, shared_preload_libraries is empty by default. Extensions such as pg_tde must be added manually.
