构建

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

BASH

pig build pkg pg_country         # 构建 RPM / DEB 包

安装

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

pig

BASH

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

dnf

BASH

dnf install -y pg_country_18       # PG 18
dnf install -y pg_country_17       # PG 17
dnf install -y pg_country_16       # PG 16
dnf install -y pg_country_15       # PG 15
dnf install -y pg_country_14       # PG 14

apt

BASH

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

创建扩展：

SQL

CREATE EXTENSION country;

用法

country: ISO 3166-1 alpha-2 国家代码类型

country 扩展提供了一个枚举数据类型，用于表示 ISO 3166-1 alpha-2 国家代码，存储开销极低。

SQL

CREATE EXTENSION country;

CREATE TABLE locations (
    id    serial PRIMARY KEY,
    code  country
);

INSERT INTO locations VALUES (1, 'US'), (2, 'GB'), (3, 'FR');

SELECT * FROM locations ORDER BY code;

数据类型

country 类型将值限制为有效的 ISO 3166-1 alpha-2 代码（两字母国家代码，如 US、GB、FR、DE 等）。无效代码在输入时会被拒绝。

运算符

支持标准比较运算符：=、<>、<、>、<=、>=。

索引支持

提供 B-tree 和 Hash 索引运算符类，可在 country 列上进行高效查询和排序。
