windyboy 2d95f87897 docs(runbooks): pgdb ops runbooks — health / restore / update + facts refresh (W1N-228)
- runbooks/pgdb-health.md: read-only health check (8 diagnostics) — containers,
  PG core + HA clients, write activity, TimescaleDB hypertables/compression,
  pgweb auth/bookmarks, daily custom-format backups, disk/fstab, logs
- runbooks/pgdb-restore.md: procedure-type restore (pg_restore -Fc, temp-DB swap,
  approval gates, rollback) — precondition command verified live
- runbooks/pgdb-update.md: gated command reference (pull -> config -q -> up -> verify;
  rollback = /opt/database/run + old volumes)
- index + validate-repo.sh classification updated; hosts/pgdb.md refreshed
  (SSH key auth works, scribe events hypertable, runbook cross-refs)

Ops notes

  • Docker compose 管理2026-08-29 改造):/opt/database/docker-compose.yml(源码在仓库 compose/pgdb/+ /opt/database/.env0600,密钥)+ /opt/database/pgweb-bookmarks/0600bookmark 含 DB 密码)。三个服务:

  • 容器内 postgres 用户 uid/gid = 70(Debian 系,非 999);迁移数据后需 chown -R 70:70
  • 密码:postgres 超级用户已换强密码(hex,存 /opt/database/.env 06002026-08-29)。HA 用 hass 角色不受影响。
  • 备份:由 pg-backup 容器接管(2026-08-29),宿主机 cron 与 /opt/database/pg-backup.sh 已退役。恢复用 pg_restorecustom format)——2026-08-29 已实测还原 hass 库 dumpstates 10014 行)成功。
  • 认证:外部连接 scram-sha-256(密码必填,改密码有效);容器内 loopback 为 trust(官方镜像默认)。
  • 回滚:旧启动命令保留在 /opt/database/run(容器无状态,数据在 /srv/pgdata);旧匿名卷 9375195843b950f4e04c34872409ca095e1136520dd019a8e86e2794be06c236(根盘 ~82M)保留作兜底,确认稳定后可 docker volume rm

Known issues

  • 2026-08-29HA 侧 HACS 集成 custom_components.scribeYAML scribe: db_url:,连 scribe 库)建表被拒(permission denied for schema publichass 无 CREATE 权限),之后持续报 relation "entities" does not exist已解决:① GRANT CREATE ON SCHEMA public TO hass;scribe 库)② 重启 HA Core 触发重跑建表。重启后自动创建 entities1591 行)/users/areas/devices/integrations/states_raw 表并启用 TimescaleDB 时间序列能力。报错已停止(最后一条 06:06 UTC),states_raw 持续写入。2026-08-29 复查:scribe 现有两个 hypertable——states_rawsegmentby metadata_id、orderby time)与 eventssegmentby event_type、orderby time),均 1 维 time;压缩已配置(timescaledb_information.compression_settings 可见对应行;2.29.x 该视图无 compression_enabled 列)。
  • hass 库的 recorder 表仍为普通表(无 hypertable);scribe 集成负责时间序列历史(states_raw + events hypertable)。

Verification history

  • 2026-08-29:首次检查(只读)+ 修复 scribe 权限 + 安装夜间备份。见 Linear vps 项目登记。
  • 2026-08-29compose 改造完成W1N-227,用户已验收):裸 docker run/opt/database/docker-compose.yml 三服务(timescaledb + pgweb + pg-backup);superuser 换强密码;端口收紧 IPv4;备份容器化(TZ=Asia/Shanghaicron 02:00 本地);pg_restore 还原实测通过;pgweb UI 用户确认可查 hass/scribe 数据。源码在仓库 compose/pgdb/
  • 2026-08-29运维 runbook 落地W1N-228,已验收):新增 runbooks/pgdb-health.md(只读,8 项诊断全绿)、pgdb-restore.md(流程式,temp-DB 安全还原 + 审批门)、pgdb-update.md(门控命令式,回滚=/opt/database/run + 旧卷);README 索引与 validate-repo.sh 分类同步更新;runbook 命令已对活主机逐条实测(含 pg_restore -l 校验当日 dump)。同日修正:SSH key auth 可用(facts 原记"密钥未安装"已过时);scribe 新增 events hypertable。
