Здравствуйте! Изучаю официальный туториал по aiohttp, появилась проблема на этапе инициализации соединения с postgresql,
conf = app['config']['postgres']
engine = await aiopg.sa.create_engine(
database=conf['database'],
user=conf['user'],
password=conf['password'],
host=conf['host'],
port=conf['port'],
minsize=conf['minsize'],
maxsize=conf['maxsize'],
)
app['db'] = engine
