DROP [ PROCEDURAL ] LANGUAGE [ IF EXISTS ] <em class="replaceable"><code>name</code></em> [ CASCADE | RESTRICT ]
</pre></div><div class="refsect1" id="id-1.9.3.117.5"><h2>Description</h2><p>
<code class="command">DROP LANGUAGE</code> removes the definition of a
previously registered procedural language. You must be a superuser
or the owner of the language to use <code class="command">DROP LANGUAGE</code>.
</p><div class="note"><h3 class="title">Note</h3><p>
As of <span class="productname">PostgreSQL</span> 9.1, most procedural
languages have been made into <span class="quote">“<span class="quote">extensions</span>”</span>, and should
therefore be removed with <a class="xref" href="sql-dropextension.html" title="DROP EXTENSION"><span class="refentrytitle">DROP EXTENSION</span></a>
not <code class="command">DROP LANGUAGE</code>.

Do not throw an error if the language 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 an existing procedural language. For backward
compatibility, the name can be enclosed by single quotes.
</p></dd><dt><span class="term"><code class="literal">CASCADE</code></span></dt><dd><p>
Automatically drop objects that depend on the language (such as
functions in the language),
and in turn all objects that depend on those objects
(see <a class="xref" href="ddl-depend.html" title="5.13. Dependency Tracking">Section 5.13</a>).
</p></dd><dt><span class="term"><code class="literal">RESTRICT</code></span></dt><dd><p>
Refuse to drop the language if any objects depend on it. This
is the default.
