<h2>Name</h2>
<p>ALTER OPERATOR CLASS — change the definition of an operator class</p>

<h2>Synopsis</h2>
<pre class="synopsis">ALTER OPERATOR CLASS <em class="replaceable"><code>name</code></em> USING <em class="replaceable"><code>index_method</code></em> RENAME TO <em class="replaceable"><code>newname</code></em>
ALTER OPERATOR CLASS <em class="replaceable"><code>name</code></em> USING <em class="replaceable"><code>index_method</code></em> OWNER TO <em class="replaceable"><code>newowner</code></em></pre>
</div>
<div class="refsect1" lang="en">
<a name="id743632"></a><h2>Description</h2>
<p> <code class="command">ALTER OPERATOR CLASS</code> changes the definition of
an operator class.
</p>
<p> You must own the operator class to use <code class="command">ALTER OPERATOR CLASS</code>.
To alter the owner, you must also be a direct or indirect member of the new
owning role, and that role must have <code class="literal">CREATE</code> privilege on
the operator class's schema. (These restrictions enforce that altering the
owner doesn't do anything you couldn't do by dropping and recreating the
operator class. However, a superuser can alter ownership of any operator
class anyway.)
</p>

<dd><p> The name (optionally schema-qualified) of an existing operator
class.
