<h2>Name</h2>

<h2>Synopsis</h2>
<pre class="synopsis">ALTER CONVERSION <em class="replaceable"><code>name</code></em> RENAME TO <em class="replaceable"><code>newname</code></em>
ALTER CONVERSION <em class="replaceable"><code>name</code></em> OWNER TO <em class="replaceable"><code>newowner</code></em></pre>
</div>
<div class="refsect1" lang="en">
<a name="id740873"></a><h2>Description</h2>
<p> <code class="command">ALTER CONVERSION</code> changes the definition of a
conversion.
</p>
<p> You must own the conversion to use <code class="command">ALTER CONVERSION</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 conversion's schema. (These restrictions enforce that altering the
owner doesn't do anything you couldn't do by dropping and recreating the
conversion. However, a superuser can alter ownership of any conversion
anyway.)
</p>
