+      Specifies that <command>VACUUM</command> should attempt to remove

+      behavior and is the default unless the
+      <literal>vacuum_index_cleanup</literal> option has been set to false
+      for the table to be vacuumed.  Setting this option to false may be
+      useful when it is necessary to make vacuum run as quickly as possible,
+      for example to avoid imminent transaction ID wraparond
+      (see <xref linkend="vacuum-for-wraparound"/>).  However, if index
+      cleanup is not performed regularly, performance may suffer, because
+      as the table is modified, indexes will accumulate dead line pointers
+      and the table itself will accumulate dead line pointers that cannot be
+      removed until index cleanup is completed.  This option has no effect
+      when <literal>FULL</literal> is used or for tables that do not have
+      an index.
