Amazon RDS for PostgreSQL expanded support to include minor versions 18.4, 17.10, 16.14, 15.18, and 14.23. These updates address known security vulnerabilities and integrate community-driven bug fixes. A key addition is the postgis_topology feature in PostGIS 3.6.3 for PostgreSQL 18, enabling users to model and query topological relationships such as network connectivity directly within databases.
The service offers streamlined upgrade processes through automatic minor version upgrades and AWS Organizations Upgrade Rollout Policy to orchestrate phased deployments. Additionally, Amazon RDS Blue/Green deployments facilitate minimizing downtime during minor version upgrades. These improvements aid users managing cloud-based PostgreSQL deployments with enhanced security and spatial querying capabilities.
