postgres-operator-best-practices skillA

postgres-operator-best-practices is agent-read markdown (skill) from air-gapped/skills: Run, configure, upgrade and troubleshoot the Zalando postgres-operator (acid.zalan.do `postgresql` CRs, Spilo, Patroni, WAL-G) on Kubernetes. Core knowledge: the v1.x -> v2.x major upgrade and its three changed defaults that bite silently (`kubernetes_use_configmaps` true, spilo-17 -> spilo-18, scram-sha-256 password encryption); the Patroni DCS living in deprecated v1 Endpoints and the split-brain hazard in switching to ConfigMaps; Helm never updating the CRDs; exactly which spec changes trigge.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add air-gapped/skills/postgres-operator-best-practices@git:20260825.21cc35f
Exact content
mdr add air-gapped/skills/postgres-operator-best-practices@sha256:17723bec4ad135fe

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
