   Description
  </title>
  <para>
   <command>DROP TABLE</command> removes tables from the database.
   Only its owner may destroy a table. A table may be emptied of rows, but not
   destroyed, by using <command>DELETE</command>.
  </para>
  <para>
   <command>DROP TABLE</command> always removes any indexes, rules,
   triggers, and constraints that exist for the target table.  However,
   to drop a table that is referenced by a foreign-key constraint of another
   table, CASCADE must be specified. (CASCADE will remove the foreign-key
   constraint, not the other table itself.)
