when i use databases.Database to connect mysql, how to change tuple result to dict ?

[weakeng]

``
from aiomysql import cursors
db = databases.Database(mysql_url, min_size=1, max_size=20,cursorclass=cursors.DictCursor)
if will raise a TypeError: row must be a sequence:
return RowProxy(metadata, row, metadata._processors, metadata._keymap)

@weakeng what makes you think cursorclass is a supported parameter?
