- 数据库主机上按实例运行 prometheus-community/postgres_exporter 0.20.1， 以实例 OS 用户走本地 socket，经 peer + ident 映射到仅有 pg_monitor 的 homelab_monitor 角色；无密码、不经 Bao。版本与官方 sha256sums.txt 同源。 - prod/dev 启用 pg_stat_statements；monitoring.yml 仅在未生效时 reload/重启 （prod 走 Patroni pending restart），重复执行 changed=0。 - 告警以上游 postgres_mixin 为底改写为 PrometheusRule，阈值对齐 Patroni failover lag 与 max_slot_wal_keep_size；抓取目标带 env 标签。 - Alertmanager 新增 env="dev" 路由到独立 dev 频道，dev SQL 检查告警补 env。 Co-Authored-By: Claude Opus 5.5 <[email protected]>
