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).

Both replicas OOMKilled at the 1Gi limit on 2026-08-23, causing a
failover and a stuck replica. Raise requests to 1Gi/250m and limits
to 2Gi/1 cpu.
