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 on other objects.
The <a class="xref" href="sql-reassign-owned.html" title="REASSIGN OWNED"><span class="refentrytitle">REASSIGN OWNED</span></a> and <a class="xref" href="sql-drop-owned.html" title="DROP OWNED"><span class="refentrytitle">DROP OWNED</span></a>
commands can be useful for this purpose; see <a class="xref" href="role-removal.html" title="21.4. Dropping Roles">Section 21.4</a>
for more discussion.
</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.
