A set of PostgeSQL functions adding highly desirable, data-type independent array functionality.
Inspired by intarray's complete disregard for all non-integer data-types.

anyarray source code, documentation and examples are available on GitHub at: https://www.github.com/JDBurnZ/anyarray
Tested on PostgreSQL 9.1, 9.2 and 9.3, but should be compatible with all versions which support arrays.
- PostgreSQL 8.x
- PostgreSQL 9.x
| Method | Returns | Description |
|---|---|---|
| anyarray_concat(anyarray, anyarray) | anyarray | Returns the first argument with values from the second argument appended to it. |
| anyarray_concat(anyarray, anynonarray) | anyarray | Returns the first argument with the second argument appended appended to it. |
| anyarray_concat_uniq(anyarray, anyarray) | anyarray | Returns the first argument with values from the second argument (which are not in the first argument) appended to it. |
| anyarray_concat_uniq(anyarray, anynonarray) | anyarray | Returns the first argument with the second argument appended to it, if the second argument isn't in the first argument. |
| anyarray_diff(anyarray, anyarray) | anyarray | Returns an array of every element which is not common between arrays. |
| anyarray_diff_uniq(anyarray, anyarray) | anyarray | Returns an array of every unique value which is not common between arrays. |
| anyarray_enumerate(anyarray) | TABLE (index bigint, value anyelement) | Unnests the array along with the indices of each element. |
| anyarray_is_array(anyelement) | boolean | Determines whether or not the argument passed is an array. |
| anyarray_numeric_only(anyarray) | anyarray | Returns the array passed with all non-numeric values removed from it. Retains whole and decimal values. |
| anyarray_ranges(anyarray) | text[] | Converts an array of values into ranges. Currently only supports smalling, integer and bigint. |
| anyarray_remove(anyarray, anyarray) | anyarray | Returns the first argument with all values from the second argument removed from it. |
| anyarray_remove(anyarray, anynonarray) | anyarray | Returns the first argument with all values matching the second argument removed from it. |
| anyarray_remove_null(anyarray) | anyarray | Returns an array with all occurrences of NULL omitted. |
| anyarray_sort(anyarray) | anyarray | Returns the array, sorted. |
| anyarray_uniq(anyarray) | anyarray | Returns an array of unique values present within the array passed. |
| Method | Returns | Description |
|---|---|---|
| anyarray_agg(anyarray) | anyarray | Concatenates arrays into a single array when aggregating. |
