## Why Both `arrstack-postgres` replicas were OOMKilled at the 1Gi memory limit on 2026-08-23 07:19, causing a failover to timeline 14, leaving replica-3 unrecoverable via pg_rewind, and blocking the argocd sync wave on Cluster Ready=False. ## Changes - Raises the CNPG Cluster resources to requests 1Gi memory / 250m CPU and limits 2Gi memory / 1 CPU **NOTE:** applying this restarts the postgres instances (CNPG rolling restart).
