This is in fact a great *feature* of Firebird, because it allows users
with old versions of applications (applications that assume old database
structure) to keep working while you upgrade the database structure.
Once you're done, users can happily close their old applications and
start new ones without breaking anything.

The only thing important is to keep the way all this works on your mind
while you alter the database structure.
