<title>Notes</title>
<para>
<command>REASSIGN OWNED</command> is often used to prepare for the
removal of one or more roles. Because <command>REASSIGN
OWNED</command> does not affect objects within other databases,
it is usually necessary to execute this command in each database
that contains objects owned by a role that is to be removed.
</para>
<para>
<command>REASSIGN OWNED</command> requires membership on both the
source role(s) and the target role.
</para>
<para>
The <link linkend="sql-drop-owned"><command>DROP OWNED</command></link> command is an alternative that
simply drops all the database objects owned by one or more roles.
</para>
<para>
The <command>REASSIGN OWNED</command> command does not affect any
privileges granted to
the <replaceable class="parameter">old_roles</replaceable> on objects
that are not owned by them. Likewise, it does not affect default
privileges created with <command>ALTER DEFAULT PRIVILEGES</command>.
Use <command>DROP OWNED</command> to revoke such privileges.
