+  <para>
+   A schema can only be dropped by its owner or a superuser.  Note that
+   the owner can drop the schema (and thereby all contained objects)
+   even if they do not own some of the objects within the schema.

+      Do not throw an error if the schema does not exist. A notice is issued

+      Automatically drop objects (tables, functions, etc.) that are
+      contained in the schema,

+      (see <xref linkend="ddl-depend"/>).

+  <title>Examples</title>
+
+  <para>
+   To remove schema <literal>mystuff</literal> from the database,

+
+<programlisting>
+DROP SCHEMA mystuff CASCADE;
+</programlisting></para>
+ </refsect1>
+
+ <refsect1>
+  <title>Compatibility</title>
+
+  <para>
+   <command>DROP SCHEMA</command> is fully conforming with the SQL
+   standard, except that the standard only allows one schema to be
+   dropped per command, and apart from the
+   <literal>IF EXISTS</literal> option, which is a <productname>PostgreSQL</productname>
+   extension.
