您可以直接安装 pg_track_settings 扩展包的预置二进制包，首先确保 PGDG 仓库已经添加并启用：

BASH

pig repo add pgdg -u          # 添加 PGDG 仓库并更新缓存

使用 pig 或者是 apt/yum/dnf 安装扩展：

安装

BASH

pig install pg_track_settings;          # 当前活跃 PG 版本安装

pig

BASH

pig ext install -y pg_track_settings -v 18  # PG 18
pig ext install -y pg_track_settings -v 17  # PG 17
pig ext install -y pg_track_settings -v 16  # PG 16
pig ext install -y pg_track_settings -v 15  # PG 15
pig ext install -y pg_track_settings -v 14  # PG 14

dnf

BASH

dnf install -y pg_track_settings_18       # PG 18
dnf install -y pg_track_settings_17       # PG 17
dnf install -y pg_track_settings_16       # PG 16
dnf install -y pg_track_settings_15       # PG 15
dnf install -y pg_track_settings_14       # PG 14

apt

BASH

apt install -y postgresql-18-pg-track-settings   # PG 18
apt install -y postgresql-17-pg-track-settings   # PG 17
apt install -y postgresql-16-pg-track-settings   # PG 16
apt install -y postgresql-15-pg-track-settings   # PG 15
apt install -y postgresql-14-pg-track-settings   # PG 14

创建扩展：

SQL

CREATE EXTENSION pg_track_settings;

用法

pg_track_settings: 追踪 PostgreSQL 配置变更

pg_track_settings 记录 PostgreSQL 配置随时间的变更，追踪全局设置（pg_settings）和按角色/数据库的覆盖设置（pg_db_role_setting）。

采集快照

定期调用（通过 cron 或 PoWA）以捕获当前设置：

SQL

SELECT pg_track_settings_snapshot();

查看某一时间点的设置

SQL

-- 指定时间的所有设置
SELECT * FROM pg_track_settings('2024-01-15 10:00:00');

-- 指定时间的所有覆盖（按角色/数据库）设置
SELECT * FROM pg_track_db_role_settings('2024-01-15 10:00:00');

比较两个时间点的设置

SQL

-- 查看最近一小时内的变更
SELECT * FROM pg_track_settings_diff(now() - interval '1 hour', now());

-- 比较覆盖设置
SELECT * FROM pg_track_db_role_settings_diff(now() - interval '1 hour', now());

查看变更历史

SQL

-- 特定设置的历史
SELECT * FROM pg_track_settings_log('work_mem');

-- 覆盖设置的历史
SELECT * FROM pg_track_db_role_settings_log('work_mem');

-- PostgreSQL 重启历史
SELECT * FROM pg_reboot;

重置历史

SQL

SELECT pg_track_settings_reset();
