title: Call procedure from different schema which has ACL privilege but caller doesn't
body: <p>One schema in our database has ACL privilege to an URL and can send requests to this URL. If I now write a procedure in this schema that sends the request and grants a <strong>different</strong> schema the option to execute this procedure, will it work or does the second schema also need the ACL privilege?</p>
  <p>I am asking to plan the necessary approach to this topic since I need to write an package in the second schema.</p>
