  <para>
   The catalog <structname>pg_foreign_table</structname> contains
   auxiliary information about foreign tables.  A foreign table is
   primarily represented by a
   <link linkend="catalog-pg-class"><structname>pg_class</structname></link>
   entry, just like a regular table.  Its <structname>pg_foreign_table</structname>
   entry contains the information that is pertinent only to foreign tables
   and not any other kind of relation.
