title: PostGIS extension not installing
body: <p>hello i was trying to install postgis to one of my database with the following command</p>
  <pre><code>CREATE EXTENSION postgis;
  </code></pre>
  <p>but it returned an error of</p>
  <p>ERROR:</p>
  <blockquote>
  <p>could not open extension control file &quot;/Library/PostgreSQL/13/share/postgresql/extension/postgis.control&quot;: No such file or directory</p>
  </blockquote>
  <p>how do i install postgis without it giving an error?</p>
  <p>UPDATE:
  I have tried it on the default databases postgres.app gives you which is your desktop username(mine is aarushsharma), i tried to do</p>
  <pre><code>CREATE EXTENSION postgis;
  </code></pre>
  <p>and it worked so i think it is a problem to do with my specific postgres user</p>
