构建

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

BASH

pig build pkg pg_orphaned         # 构建 RPM / DEB 包

安装

您可以直接安装 pg_orphaned 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_orphaned;          # 当前活跃 PG 版本安装

pig

BASH

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

dnf

BASH

dnf install -y pg_orphaned_18       # PG 18
dnf install -y pg_orphaned_17       # PG 17
dnf install -y pg_orphaned_16       # PG 16
dnf install -y pg_orphaned_15       # PG 15
dnf install -y pg_orphaned_14       # PG 14

apt

BASH

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

创建扩展：

SQL

CREATE EXTENSION pg_orphaned;

用法

pg_orphaned: 处理孤立文件

pg_orphaned 提供检测和管理 PostgreSQL 中孤立数据文件的函数。它通过使用脏快照处理进行中的事务可能导致误报的边角情况。

列出孤立文件

SQL

-- 列出孤立文件（默认：超过 1 天的标记为 "older"）
SELECT * FROM pg_list_orphaned();

-- 自定义时间阈值
SELECT * FROM pg_list_orphaned('10 seconds');
SELECT * FROM pg_list_orphaned('1 minute');

返回：dbname、path、name、size、mod_time、relfilenode、reloid、older（布尔值）。

将孤立文件移至备份

SQL

-- 将超过阈值的文件移动到 orphaned_backup 目录
SELECT pg_move_orphaned('1 minute');

列出已移动的文件

SQL

SELECT * FROM pg_list_orphaned_moved();

将文件移回（如果仍然是孤立的）

SQL

SELECT pg_move_back_orphaned();

删除已移动的文件

SQL

SELECT pg_remove_moved_orphaned();

典型工作流程

SQL

-- 1. 检查孤立文件
SELECT * FROM pg_list_orphaned('1 minute');

-- 2. 将它们移到备份（仅超过阈值的）
SELECT pg_move_orphaned('1 minute');

-- 3. 验证移动了什么
SELECT * FROM pg_list_orphaned_moved();

-- 4. 确认后删除备份文件
SELECT pg_remove_moved_orphaned();

注意：函数操作的是你当前连接的数据库中的孤立文件。在移动或删除文件前请务必仔细检查。
