The RowProxy object is more intelligent than a plain tuple. As well as accessing the values by index, you can use your original column objects or the name of the column to retrieve the values from it. You can also use attribute access rather than indexing. Eg. row['your_column_name'] row[your_column] row.your_column_name I imagine this would make it harder to pickle.
