+  In some cases you may wish to know which table a particular tuple
+  originated from. There is a system attribute called
+  <quote>TABLEOID</quote> in each table which can tell you the
+  originating table:
+
+   <programlisting>
+    SELECT c.tableoid, c.name, c.altitude
+    FROM cities c
+    WHERE c.altitude > 500;
+   </programlisting>
