I've added this to the COPY notes section:

   <para>
    <command>COPY</command> only deals with the specific table named;
    it does not copy data to or from child tables.  Thus for example
    <literal>COPY <replaceable class="parameter">table</> TO</literal>
    shows the same data as <literal>SELECT * FROM ONLY <replaceable
    class="parameter">table</></literal>.  But <literal>COPY
    (SELECT * FROM <replaceable class="parameter">table</>) TO ...</literal>
    can be used to dump all of the data in an inheritance hierarchy.
   </para>

			regards, tom lane
