Of course. I always test my theories in a controlled scientific

True. But it wasn't the developer that messed with the
RDB$Relation_Fields.RDB$Null_Flag to break it. That's kinda like
blaming God for giving us the freadom to do what we will.

Reminds me of a limerick:

There once was a lass from Cape Cod,
who thought all children came from God.
But it wasn't the Almighty,
that lifted her nighty.
It was Roger the Lodger,
