Actually, it's not a big deal to implement native BOOLEAN datatype. But if
we want to follow the SQL specification, then it's necessary to implement
the boolean logic as well (e.g. predicates like WHERE BOOLEAN_FIELD or
assignments like BOOLEAN_FIELD = FIELD IS NULL). It's not a trivial task and
Borland failed to do this in their IB 7.0, although promised to. This work
is in our to-do list, but it doesn't have a high priority.
