I hacked on the postgres ltree extension [1] recently, and was amazed at how easy it is to extend functionality of the database, add new types&amp;#x2F;operators&amp;#x2F;etc. I think if they were a bit more accessible we&amp;#x27;d see them much more. You can even write them in go [2]&lt;p&gt;[1] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;postgres&amp;#x2F;postgres&amp;#x2F;tree&amp;#x2F;master&amp;#x2F;contrib&amp;#x2F;ltree&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;postgres&amp;#x2F;postgres&amp;#x2F;tree&amp;#x2F;master&amp;#x2F;contrib&amp;#x2F;ltr...&lt;/a&gt;&lt;p&gt;[2] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;microo8&amp;#x2F;plgo&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;github.com&amp;#x2F;microo8&amp;#x2F;plgo&lt;/a&gt;</text></comment>

Everything is very clearly written and documented. It&amp;#x27;s pretty easy to read the source code to get an understanding of how components of Postgres work under the hood.</text></comment>
