+ <command>DROP TABLE</command> removes tables from the database.
+ Only the table owner, the schema owner, and superuser can drop a
+ table. To empty a table of rows
+ without destroying the table, use <link linkend="sql-delete"><command>DELETE</command></link>
+ or <link linkend="sql-truncate"><command>TRUNCATE</command></link>.
+ </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 view or a foreign-key
+ constraint of another table, <literal>CASCADE</literal> must be
+ specified. (<literal>CASCADE</literal> will remove a dependent view entirely,
+ but in the foreign-key case it will only remove the foreign-key
+ constraint, not the other table entirely.)
