pg_free_result — Free result memory

### Description

> Note:

> This function used to be called pg_freeresult().

### Parameters

`result`

  PostgreSQL query result resource, returned by pg_query(), pg_query_params() or pg_execute() (among others).

### Return Values

Returns `TRUE` on success or `FALSE` on failure.

### Examples

Example #1 pg_free_result() example

`<?php
$db = pg_connect("dbname=users user=me") || die();
$res = pg_query($db, "SELECT 1 UNION ALL SELECT 2");
$val = pg_fetch_result($res, 1, 0);
echo "First field in the second row is: ", $val, "\n";
pg_free_result($res);
?>`

The above example will output:

    First field in the second row is: 2
