There is what may actually be a mistake in our markup. The problem is in a situation like <para> <command>FOO</command> is ... there is strictly speaking a line break before "FOO". In the HTML output, this does not appear to be a problem, but in the man page output, this shows up, so you get double blank lines at odd places. So far, we have attempted to work around this with an XSL hack, but that causes other problems, such as creating run-ins in places like <acronym>SQL</acronym> <command>COPY</command> So fix the problem properly by removing the extra whitespace. I only fixed the problems that affect the man page output, not all the places.

<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

privilege requirements than <productname>PostgreSQL</productname> uses.
