  <para>
   The catalog <structname>pg_init_privs</structname> records information about
   the initial privileges of objects in the system.  There is one entry
   for each object in the database which has a non-default (non-NULL)
   initial set of privileges.
  </para>

  <para>
   Objects can have initial privileges either by having those privileges set
   when the system is initialized (by <application>initdb</application>) or when the
   object is created during a <link linkend="sql-createextension"><command>CREATE EXTENSION</command></link> and the
   extension script sets initial privileges using the <link linkend="sql-grant"><command>GRANT</command></link>
   system.  Note that the system will automatically handle recording of the
   privileges during the extension script and that extension authors need
   only use the <command>GRANT</command> and <command>REVOKE</command>
   statements in their script to have the privileges recorded.  The
   <literal>privtype</literal> column indicates if the initial privilege was
   set by <application>initdb</application> or during a
   <command>CREATE EXTENSION</command> command.
  </para>

  <para>
   Objects which have initial privileges set by <application>initdb</application> will
   have entries where <literal>privtype</literal> is
   <literal>'i'</literal>, while objects which have initial privileges set
   by <command>CREATE EXTENSION</command> will have entries where
   <literal>privtype</literal> is <literal>'e'</literal>.
