Проблема с asyncio и asyncpg

Подскажите пожалуйста в чём проблема следующего кода:

import asyncio

import asyncpg


class DataBase:
    def __init__(self, pool):
        self.pool = pool

    async def fetchone(self, query, *args):
        async with self.pool.acquire() as connection:
            result = await connection.fetchrow(query, *args)
            return result

    async def fetchall(self, query, *args):
        async with self.pool.acquire() as connection:
            result = await connection.fetch(query, *args)
            return result

    async def update(self, query, *args):
        async with self.pool.acquire() as connection:
            result = await connection.fetch(query, *args)
            return result


async def on_startup():
    print('Started')
    db_pool = await asyncpg.create_pool(
        host='localhost',
        port=5432,
        user='postgres',
        password='password',
        database='project'
    )
    print(db_pool)


async def some_async_function():
    print('++')


async def some_other_async_function():
    print('+')


async def main():
    try:
        await on_startup()
        await some_async_function()
        await some_other_async_function()
    except Exception as err:
        print(err)
    finally:
        pass


if __name__ == '__main__':
    asyncio.run(main())

Если не пытаться создать пул соединений то код работает без ошибок Но если с ним то получается в от такая ошибка: Exception ignored in: <function _ProactorBasePipeTransport.del at 0x00000244550C92D0>
