构建

您可以使用 pig build 命令构建 md5hash 扩展的 RPM / DEB 包：

BASH

pig build pkg md5hash         # 构建 RPM / DEB 包

安装

您可以直接安装 md5hash 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 md5hash;          # 当前活跃 PG 版本安装

pig

BASH

pig ext install -y md5hash -v 18  # PG 18
pig ext install -y md5hash -v 17  # PG 17
pig ext install -y md5hash -v 16  # PG 16
pig ext install -y md5hash -v 15  # PG 15
pig ext install -y md5hash -v 14  # PG 14

dnf

BASH

dnf install -y md5hash_18       # PG 18
dnf install -y md5hash_17       # PG 17
dnf install -y md5hash_16       # PG 16
dnf install -y md5hash_15       # PG 15
dnf install -y md5hash_14       # PG 14

apt

BASH

apt install -y postgresql-18-md5hash   # PG 18
apt install -y postgresql-17-md5hash   # PG 17
apt install -y postgresql-16-md5hash   # PG 16
apt install -y postgresql-15-md5hash   # PG 15
apt install -y postgresql-14-md5hash   # PG 14

创建扩展：

SQL

CREATE EXTENSION md5hash;

用法

md5hash: PostgreSQL 原生 MD5 哈希数据类型

md5hash 扩展提供了高效的 128 位数据类型，以二进制格式（16 字节）而非文本格式（32+ 字节）存储 MD5 哈希值。

SQL

CREATE EXTENSION md5hash;

CREATE TABLE test_table (
    id md5hash PRIMARY KEY
);

INSERT INTO test_table VALUES ('c4ca4238a0b923820dcc509a6f75849b');

SELECT * FROM test_table
WHERE id = 'c4ca4238a0b923820dcc509a6f75849b';

运算符

支持标准比较运算符：=、<>、<、>、<=、>=。

索引支持

内置 Btree 索引运算符类，可在 md5hash 列上实现高效查找和主键约束。

存储优势

与以 text 类型存储 MD5 相比，md5hash 类型大约节省 40% 的存储空间，并且索引查找速度更快。
