Row is a namedtuple, the dictionary is extracted from a database with
a row factory so the namedtuple names are the column names. It means
that if I change a column name then most things continue to work
without any code changes, and also I can refer to items in the tuple
by name of course.
I have the answer to my question in other responses.
