I wouldn't mind such a change myself, however what about all the installations where people do while (*fetch_row() !== false) ?
Wouldn't it be a lot easier to do it the other way around ?
I mean, the semantics of returning false when a fetch cannot be executed
because aren't any rows left is perfectly clear, and returning NULL when the result cannot be determined (because of an error) is also better than returning any other value (like 'false').
This would also be easier to carry out while maintaining BC.
