  <para>
   A <structname>pg_default_acl</structname> entry shows the initial privileges to
   be assigned to an object belonging to the indicated user.  There are
   currently two types of entry: <quote>global</quote> entries with
   <structfield>defaclnamespace</structfield> = zero, and <quote>per-schema</quote> entries
   that reference a particular schema.  If a global entry is present then
   it <emphasis>overrides</emphasis> the normal hard-wired default privileges
   for the object type.  A per-schema entry, if present, represents privileges
   to be <emphasis>added to</emphasis> the global or hard-wired default privileges.
  </para>

  <para>
   Note that when an <acronym>ACL</acronym> entry in another catalog is null,
   it is taken to represent the hard-wired default privileges for its object,
   <emphasis>not</emphasis> whatever might be in <structname>pg_default_acl</structname>
   at the moment.  <structname>pg_default_acl</structname> is only consulted during
   object creation.
