The same thing seems to be true in various other pages:
git grep 'WITH.*value' doc

In addition to WITH, it's also true of SET:

git grep -F '[= <replaceable class="parameter">value' doc/src/sgml/ref/alter_index.sgml
doc/src/sgml/ref/alter_table.sgmldoc/src/sgml/ref/create_materialized_view.sgml
doc/src/sgml/ref/create_publication.sgmldoc/src/sgml/ref/create_subscription.sgml
 

Note that some utility statements (analyze,cluster,vacuum,reindex) which
have parenthesized syntax with booleans say this:
| The boolean value can also be omitted, in which case TRUE is assumed.

BTW, in your patch:
+     <para>
+      A <type>boolean</type> parameter can omit the value. This is equivalent
+      to assigning the parameter to <literal>true</literal>.
+     </para>
+     <para>

should say: "The value can be omitted, which is equivalent to specifying
TRUE".
