Return a range of elements from an array in Postgres json
<p>As known, in Postgres json, we can get one element at a specified index from an array using this:</p>

<pre><code>["a","b","c"]::json -&gt; 2
</code></pre>

<p>The script above return the 3rd element "c".</p>

<p>Then is there any way a range of elements can be returned if I specify a index range such as 0 to 20?</p>
