<para>
A character string domain that contains
either <literal>YES</literal> or <literal>NO</literal>. This
is used to represent Boolean (true/false) data in the
information schema. (The information schema was invented
before the type <type>boolean</type> was added to the SQL
standard, so this convention is necessary to keep the
information schema backward compatible.)

Every column in the information schema has one of these four types.
</para>
<para>
Boolean (true/false) data is represented in the information schema
by a column of type <type>character_data</type> that contains
either <literal>YES</literal> or <literal>NO</literal>. (The
information schema was invented before the type
<type>boolean</type> was added to the SQL standard, so this
convention is necessary to keep the information schema backward
compatible.)
Every column in the information schema has one of these five types.
