I'm looking at the insert_node() method, and whilst I understand it's meant primarily for internal use, it looks like if I make a typo when I am supplying the data, I'll end up with a gap in my tree. Is that correct?
I was wondering whether it might be better to run those two update queries after the data has been inserted successfully. What do you think? If you did this, you'd have to expand on the two update queries, so that they ignore the newly inserted row.
