CREATE EXTENSION arraymath;

Usage

arraymath: element-by-element array operations for PostgreSQL

Provides element-by-element operators and utility functions for integer, float, and numeric arrays.

CREATE EXTENSION arraymath;

Operators

All operators are prefixed with @ to indicate element-by-element behavior. Works with array-vs-array (same length or cycling) and array-vs-scalar.

Operator	Description	Returns
`@=`	Element-by-element equality	`boolean[]`
`@<`	Element-by-element less than	`boolean[]`
`@>`	Element-by-element greater than	`boolean[]`
`@<=`	Element-by-element less than or equals	`boolean[]`
`@>=`	Element-by-element greater than or equals	`boolean[]`
`@+`	Element-by-element addition	same type
`@-`	Element-by-element subtraction	same type
`@*`	Element-by-element multiplication	same type
`@/`	Element-by-element division	same type

Functions

Function	Description
`array_sum(anyarray)`	Sum of all elements
`array_avg(anyarray)`	Average of all elements
`array_min(anyarray)`	Minimum element
`array_max(anyarray)`	Maximum element
`array_median(anyarray)`	Median element
`array_sort(anyarray)`	Sort ascending
`array_rsort(anyarray)`	Sort descending

Examples

-- Array vs scalar
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}

-- Array vs array (cycling shorter array)
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}

-- Utility functions
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
