/ 20 июня 2020

Я пытаюсь создать пул db, но все время получаю ошибку подключения (я думаю). Приветствуется любая помощь, а также ссылки на документацию, которую я могу прочитать, поскольку я новичок в postgresql. Заранее спасибо. Код: 

async def create_db_pool():
    bot.pg_con = await asyncpg.create_pool(user="postgres", password="placeholder", database="testDB")
