title: How to install libpq-fe.h?
body: <p>I cannot figure this out for the life of me.</p>
  <p>When I <code>pip install django-tenant-schemas</code> it tries to install the dependency <code>psycopg2</code> which requires the Python headers and gcc. I have all this installed and still keep getting this error!</p>
  <pre><code>./psycopg/psycopg.h:35:10: fatal error: libpq-fe.h: No such file or directory
  </code></pre>
  <p>So to install <code>libpq-fe-h</code> I need to <code>sudo apt-get install libpq-dev</code>..</p>
  <p>..which returns..</p>
  <pre><code>libpq-dev is already the newest version (10.10-0ubuntu0.18.04.1).
  </code></pre>
  <p>Then when I <code>sudo find / libpq-fe.h</code> it doesn't seem to be in my OS.</p>
  <p>I am lost at this point. If anyone can help I would highly appreciate it.</p>
