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>
