构建

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

BASH

pig build pkg pg_hashlib         # 构建 RPM / DEB 包

安装

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

pig

BASH

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

dnf

BASH

dnf install -y pg_hashlib_18       # PG 18
dnf install -y pg_hashlib_17       # PG 17
dnf install -y pg_hashlib_16       # PG 16
dnf install -y pg_hashlib_15       # PG 15
dnf install -y pg_hashlib_14       # PG 14

apt

BASH

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

创建扩展：

SQL

CREATE EXTENSION hashlib;

用法

hashlib: PostgreSQL 的稳定哈希函数库

提供实现不会随 PostgreSQL 版本变化的稳定哈希函数。

字符串哈希（32 位）

SQL

SELECT hash_string('hello', 'crc32');
SELECT hash_string('hello', 'murmur3');

使用可选的初始值：

SQL

SELECT hash_string('hello', 'crc32', 42);

字符串哈希（64 位）

SQL

SELECT hash64_string('hello', 'city64');
SELECT hash64_string('hello', 'siphash24');
SELECT hash64_string('hello', 'lookup3');

字符串哈希（128 位）

SQL

SELECT hash128_string('hello', 'md5');
SELECT hash128_string('hello', 'city128');
SELECT hash128_string('hello', 'spooky');

整数哈希

SQL

SELECT hash_int4(42);        -- 32 位整数的 32 位哈希
SELECT hash_int8(42::bigint); -- 64 位整数的 64 位哈希

可用算法

算法	CPU 无关	位数	描述
`crc32`	是	32	CRC32
`murmur3`	否	32	MurmurHash v3
`md5`	是	128	MD5
`city64`	否	64	CityHash64
`city128`	否	128	CityHash128
`siphash24`	是	64	SipHash-2-4
`spooky`	否	128	SpookyHash
`lookup2`	否	64	Jenkins lookup2
`lookup3`	否	64	Jenkins lookup3 CPU 原生字节序
`lookup3be`	是	64	Jenkins lookup3 大端字节序
`lookup3le`	是	64	Jenkins lookup3 小端字节序
`pgsql84`	否	64	Postgres 8.4+ 中修改的 lookup3

整数算法：wang32、wang32mult、jenkins（32 位）；wang64、wang64to32（64 位）。所有整数算法都是可逆的（1:1 映射），适合在唯一 ID 上创建随机排序。
