To some extent I just want to stay away from the poltics.  Search the
web to see the controversy over lambda.  Besides, I do find the second
line below clearer than the first.

self.row_factory = lambda cur, row: row
def row_factory(cur, row): return row

In fact, let's make your comment a docstring:

def row_factory(cur, row):
    """you can overwrite this with a custom row factory
       e.g. a dict_factory

       cursor = pgdbCursor(src, cache)
       def cursor.row_factory(caller, row):
           d = {}
           for idx, col in enumerate(caller.description):
               d[col[0]] = row[idx]
           return d
    """
    return row
