DocBook XML is superficially compatible with DocBook SGML but has a slightly stricter DTD that we have been violating in a few cases. Although XSLT doesn't care whether the document is valid, the style sheets don't necessarily process invalid documents correctly, so we need to work toward fixing this. This first commit moves the indexterms in refentry elements to an allowed position. It has no impact on the output.

<para>

<command>DROP ROLE</command> removes the specified role(s).
|
|
To drop a superuser role, you must be a superuser yourself;
|
|
to drop non-superuser roles, you must have <literal>CREATEROLE</>
|
|
privilege.
|
|
</para>
|
|
|
|
<para>
|
|
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. The <xref
|
|
linkend="sql-reassign-owned">
|
|
and <xref linkend="sql-drop-owned">
|
|
commands can be useful for this purpose.
|
|
</para>
|
|
|
|
<para>
|
|
However, it is not necessary to remove role memberships involving
|
|
the role; <command>DROP ROLE</> 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.

only one role to be dropped at a time, and it specifies different
