pg_init_privs
   The catalog pg_init_privs 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.
  
   Objects can have initial privileges either by having those privileges set
   when the system is initialized (by initdb) or when the
   object is created during a CREATE EXTENSION and the
   extension script sets initial privileges using the GRANT
   system.  Note that the system will automatically handle recording of the
   privileges during the extension script and that extension authors need
   only use the GRANT and REVOKE
   statements in their script to have the privileges recorded.  The
   privtype column indicates if the initial privilege was
   set by initdb or during a
   CREATE EXTENSION command.
  
   Objects which have initial privileges set by initdb will
   have entries where privtype is
   'i', while objects which have initial privileges set
   by CREATE EXTENSION will have entries where
   privtype is 'e'.
