Well, actually it says
<para>
<productname>Postgres</productname> supports the
<acronym>SQL99</acronym> <type>boolean</type> type.
<type>boolean</type> can have one of only two states: 'true' or
'false'. A third state, 'unknown', is represented by the SQL NULL
state. <type>boolean</type> can be used in any boolean expression,
and boolean expressions always evaluate to a result compatible
with this type.
</para>
but <type> doesn't actually alter the font. Maybe monospaced would be
appropriate? Actually, the issue might be served better by showing an
example.

I understand.
