DROP SCHEMA [ IF EXISTS ] <em class="replaceable"><code>name</code></em> [, ...] [ CASCADE | RESTRICT ]
</pre></div><div class="refsect1" id="id-1.9.3.129.5"><h2>Description</h2><p>
<code class="command">DROP SCHEMA</code> removes schemas from the database.
</p><p>
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.
</p></div><div class="refsect1" id="id-1.9.3.129.6"><h2>Parameters</h2><div class="variablelist"><dl class="variablelist"><dt><span class="term"><code class="literal">IF EXISTS</code></span></dt><dd><p>
Do not throw an error if the schema does not exist. A notice is issued
in this case.
</p></dd><dt><span class="term"><em class="replaceable"><code>name</code></em></span></dt><dd><p>
The name of a schema.
</p></dd><dt><span class="term"><code class="literal">CASCADE</code></span></dt><dd><p>
Automatically drop objects (tables, functions, etc.) that are
contained in the schema,
and in turn all objects that depend on those objects
(see <a class="xref" href="ddl-depend.html" title="5.14. Dependency Tracking">Section 5.14</a>).
</p></dd><dt><span class="term"><code class="literal">RESTRICT</code></span></dt><dd><p>
Refuse to drop the schema if it contains any objects. This is
the default.
</p></dd></dl></div></div><div class="refsect1" id="id-1.9.3.129.7"><h2>Notes</h2><p>
Using the <code class="literal">CASCADE</code> option might make the command
remove objects in other schemas besides the one(s) named.
</p></div><div class="refsect1" id="id-1.9.3.129.8"><h2>Examples</h2><p>
To remove schema <code class="literal">mystuff</code> from the database,
along with everything it contains:
</p><pre class="programlisting">
DROP SCHEMA mystuff CASCADE;
</pre></div><div class="refsect1" id="id-1.9.3.129.9"><h2>Compatibility</h2><p>
<code class="command">DROP SCHEMA</code> is fully conforming with the SQL
standard, except that the standard only allows one schema to be
dropped per command, and apart from the
<code class="literal">IF EXISTS</code> option, which is a <span class="productname">PostgreSQL</span>
extension.
