Amazon Aurora PostgreSQL-compatible edition now supports zero-downtime patching (ZDP). With ZDP, customers can upgrade to a new PostgreSQL version and apply patches to their Aurora cluster without any downtime.

ZDP preserves client connections while the database engine restarts. This feature allows you to more frequently upgrade your clusters to newer PostgreSQL minor versions while maintaining business continuity. ZDP is enabled on all Aurora clusters running supported database versions in all regions when you upgrade database minor versions or apply patches. Please review the Aurora documentation for more details.

Amazon Aurora is designed for unparalleled high performance and availability at global scale with full MySQL and PostgreSQL compatibility. It provides built-in security, continuous backups, serverless compute, up to 15 read replicas, automated multi-Region replication, and integrations with other AWS services.
