<h2>Name</h2>
<p>DROP ROLE — remove a database role</p>
</div>
<a name="id771948"></a><div class="refsynopsisdiv">
<h2>Synopsis</h2>
<pre class="synopsis">DROP ROLE <em class="replaceable"><code>name</code></em> [, ...]</pre>
</div>
<div class="refsect1" lang="en">
<a name="id771972"></a><h2>Description</h2>
<p> <code class="command">DROP ROLE</code> removes the specified role(s).
To drop a superuser role, you must be a superuser yourself;
to drop non-superuser roles, you must have <code class="literal">CREATEROLE</code>
privilege.
</p>
<p> A role cannot be removed if it is still referenced in any database
of the cluster; an error will be raised if so. Before dropping the role,
you must drop all the objects it owns (or reassign their ownership)
and revoke any privileges the role has been granted.
</p>
<p> However, it is not necessary to remove role memberships involving
the role; <code class="command">DROP ROLE</code> automatically revokes any memberships
of the target role in other roles, and of other roles in the target role.
The other roles are not dropped nor otherwise affected.
</p>

<div class="variablelist"><dl>
<dt><span class="term"><em class="replaceable"><code>name</code></em></span></dt>
<dd><p> The name of the role to remove.
</p></dd>
</dl></div>

<div class="refsect1" lang="en">
<a name="id772032"></a><h2>Notes</h2>
<p> <span class="productname">PostgreSQL</span> includes a program <a href="app-dropuser.html"><span class="application">dropuser</span></a> that has the
same functionality as this command (in fact, it calls this command)
but can be run from the command shell.
</p>
</div>
<div class="refsect1" lang="en">
<a name="id772060"></a><h2>Examples</h2>
<p> To drop a role:
</p>
<pre class="programlisting">DROP ROLE jonathan;</pre>
<p>
</p>
</div>
<div class="refsect1" lang="en">
<a name="id772074"></a><h2>Compatibility</h2>
<p> The SQL standard defines <code class="command">DROP ROLE</code>, but it allows
only one role to be dropped at a time, and it specifies different
privilege requirements than <span class="productname">PostgreSQL</span> uses.
</p>
