+  <para>
+   <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 <xref linkend="sql-delete"/>
+   or <xref linkend="sql-truncate"/>.
+  </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.)

+  <para>
+   This command conforms to the SQL standard, except that the standard only
+   allows one table to be dropped per command, and apart from the
+   <literal>IF EXISTS</literal> option, which is a <productname>PostgreSQL</productname>
+   extension.
