构建

您可以使用 pig build 命令构建 pg_upless 扩展的 RPM / DEB 包：

BASH

pig build pkg pg_upless         # 构建 RPM / DEB 包

安装

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

BASH

pig repo add pgsql -u          # 添加仓库并更新缓存

使用 pig 或者是 apt/yum/dnf 安装扩展：

安装

BASH

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

pig

BASH

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

dnf

BASH

dnf install -y pg_upless_18       # PG 18
dnf install -y pg_upless_17       # PG 17
dnf install -y pg_upless_16       # PG 16
dnf install -y pg_upless_15       # PG 15
dnf install -y pg_upless_14       # PG 14

apt

BASH

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

创建扩展：

SQL

CREATE EXTENSION pg_upless CASCADE;  -- 依赖: plpgsql

用法

pg_upless: 检测无效 UPDATE

pg_upless 检测不改变任何实际值的 UPDATE 语句（ORM 中常见）。它通过在监控表上安装触发器并收集统计信息来工作。它作为诊断工具使用，不适合长期启用。

开始监控

SQL

-- 监控特定表
SELECT pg_upless_start('public', 'boats');

-- 监控模式中的所有表
SELECT pg_upless_start('public');

停止监控

SQL

-- 停止监控特定表
SELECT pg_upless_stop('public', 'boats');

-- 停止监控模式中的所有表
SELECT pg_upless_stop('public');

查看统计信息

该扩展在 pg_upless 模式中创建两个表：

pg_upless_stats – 存储每个表的总更新次数与无效更新次数
pg_upless_start_time – 记录监控开始时间（用于速率计算）
