·8 mins
CloudNativePG 1.26 introduces enhanced support for Kubernetes startup probes,
giving users finer control over how and when PostgreSQL instances are marked as

practical guidance for improving the reliability of high-availability Postgres
clusters by aligning startup conditions with actual database readiness.
