List grants and privileges for a materialized view in PostgreSQL
<p>I need to determine what privileges are currently granted for some materialized views in my database.</p>

<p>The query to do this for a table or standard view is pretty straight forward:</p>

<pre><code>SELECT grantee, string_agg(privilege_type, ', ') AS privileges
FROM information_schema.table_privileges
WHERE table_schema = 'some_schema' AND table_name = 'some_table'
GROUP by grantee;
</code></pre>

<p>That said, there doesn't seem to be an analogous table for materialized views. Where does PostgreSQL store this information?</p>
