构建

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

BASH

pig build pkg pg_arraymath         # 构建 RPM / DEB 包

安装

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

pig

BASH

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

dnf

BASH

dnf install -y pg_arraymath_18       # PG 18
dnf install -y pg_arraymath_17       # PG 17
dnf install -y pg_arraymath_16       # PG 16
dnf install -y pg_arraymath_15       # PG 15
dnf install -y pg_arraymath_14       # PG 14

apt

BASH

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

创建扩展：

SQL

CREATE EXTENSION arraymath;

用法

arraymath: PostgreSQL 的逐元素数组运算

提供整数、浮点数和数值数组的逐元素运算符和工具函数。

SQL

CREATE EXTENSION arraymath;

运算符

所有运算符以 @ 为前缀，表示逐元素操作。支持数组对数组（相同长度或循环扩展）以及数组对标量。

运算符	说明	返回类型
`@=`	逐元素相等	`boolean[]`
`@<`	逐元素小于	`boolean[]`
`@>`	逐元素大于	`boolean[]`
`@<=`	逐元素小于等于	`boolean[]`
`@>=`	逐元素大于等于	`boolean[]`
`@+`	逐元素加法	同类型
`@-`	逐元素减法	同类型
`@*`	逐元素乘法	同类型
`@/`	逐元素除法	同类型

函数

函数	说明
`array_sum(anyarray)`	所有元素之和
`array_avg(anyarray)`	所有元素的平均值
`array_min(anyarray)`	最小元素
`array_max(anyarray)`	最大元素
`array_median(anyarray)`	中位数元素
`array_sort(anyarray)`	升序排序
`array_rsort(anyarray)`	降序排序

示例

SQL

-- 数组与标量
SELECT ARRAY[1,2,3,4] @< 4;             -- {t,t,t,f}
SELECT ARRAY[3.4,5.6,7.6] @* 8.1;       -- {27.54,45.36,61.56}

-- 数组与数组（较短数组循环扩展）
SELECT ARRAY[1,2,3,4,5,6] @* ARRAY[1,2]; -- {1,4,3,8,5,12}
SELECT ARRAY[1,2,3] @= ARRAY[3,2,1];     -- {f,t,f}

-- 工具函数
SELECT array_sort(ARRAY[9,1,8,2,7]);     -- {1,2,7,8,9}
SELECT array_sum(ARRAY[1,2,3,4,5]);      -- 15
SELECT array_median(ARRAY[1,2,3,4,5]);   -- 3
