The data for that notes field is probably making the overall size of the query
too big for the backend to handle. It has a limit of around 8k. The real
solution is to have the driver use a large object instead of in-line the data.
I know I have said this before, but I will try to add that option next since it
seems to be really necessary now, alot of people need to store large amounts of
character data.
