OT: that would be useful for another reason.
Firebird 3 will introduce the BOOLEAN datatype and other innovations
(encrypted connections, etc).
Interbase has had BOOLEAN support for a while now.

It would be nice to be able to support new functionality without
sacrificing the ability to connect to older clients.

Of course, this has an obvious parallel to the mysql4....5...6 units;
sorry that I don't know how things are handled there; I've stayed away
from them as much as possible...
