body: <p>im trying to create a tablespace and keep getting the same error</p>
  
  <pre><code>pablo@MisCompras-dev:~$ psql -d postgres -U pablo
  psql (11.2 (Ubuntu 11.2-1.pgdg18.04+1))
  Type "help" for help.
  postgres=# create tablespace miscompras_space owner pablo location '/home/pablo/postgres';
  ERROR:  could not set permissions on directory "/home/pablo/postgres": Operation not permitted
  </code></pre>
  
  <p>i set the permissions of /home, /home/pablo, and /home/pablo/postgres to 777 and got the same error when creating a tablespace.</p>
  
  <p>i also added pablo to the access control list of those three directories with the following command: </p>
  
  <pre><code>setfacl -m pablo:rwx [directory]
  </code></pre>
  
  <p>when i type:</p>
  
  <pre><code>getfacl [directory]
  </code></pre>
  
  <p>user:pablo:rwx appears for all 3. what am i doing wrong? thanks in advance</p>
