构建

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

BASH

pig build pkg pg_geohash         # 构建 RPM / DEB 包

安装

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

pig

BASH

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

dnf

BASH

dnf install -y pg_geohash_18       # PG 18
dnf install -y pg_geohash_17       # PG 17
dnf install -y pg_geohash_16       # PG 16
dnf install -y pg_geohash_15       # PG 15
dnf install -y pg_geohash_14       # PG 14

apt

BASH

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

创建扩展：

SQL

CREATE EXTENSION pg_geohash;

用法

pg_geohash: PostgreSQL 的 Geohash 函数

基于 C 实现的 PostgreSQL Geohash 函数（同时支持 HAWQ 和 Greenplum）。基于 libgeohash C 库。

Geohash 背景知识：维基百科：Geohash

函数

将经纬度编码为指定精度的 geohash 字符串：

SQL

SELECT LAT_LON_TO_GEOHASH_WITH_LEN(latitude, longitude, 5) AS geohash;

将经纬度编码为全精度的 geohash：

SQL

SELECT LAT_LON_TO_GEOHASH(latitude, longitude) AS geohash;

将 geohash 解码回经纬度：

SQL

SELECT GEOHASH_TO_LAT_LON('dp3w7') AS lat_lon;

示例

使用 5 字符精度（约 2.4km x 4.9km 网格）计算基于 geohash 的聚合：

SQL

SELECT LAT_LON_TO_GEOHASH_WITH_LEN(latitude, longitude, 5) AS geohash,
       COUNT(*)
FROM crimes
GROUP BY 1
ORDER BY 2 DESC
LIMIT 10;

 geohash | count
---------+-------
 dp3w7   | 72404
 dp3tt   | 70713
 dp3tw   | 63642
 dp3wm   | 62332
 dp3wk   | 56467

从 geohash 恢复坐标：

SQL

SELECT location,
       GEOHASH_TO_LAT_LON(LAT_LON_TO_GEOHASH(latitude, longitude))
FROM crimes
LIMIT 5;
