OverflowError: date value out of range

• asyncpg version: 0.18.3
• PostgreSQL version: 10.7
• Do you use a PostgreSQL SaaS? If so, which? Can you reproduce
  the issue with a local PostgreSQL install?: Yes
• Python version: 3.7
• Platform: Mac OS
• Do you use pgbouncer?: No
• Did you install asyncpg with pip?: Yes
• If you built asyncpg locally, which version of Cython did you use?:
• Can the issue be reproduced under both asyncio and
  uvloop?:

asyncpg is failing to parse timestamp

code:

import asyncio
import asyncpg

async def run():
    conn = await asyncpg.connect(user='secure', password='secure',
                                 database='secure',
                                 host='secure.com', port=15432, timeout=600)

    values = await conn.fetch('''SELECT  _ts FROM Events''')
    print(values)
    await conn.close()


loop = asyncio.get_event_loop()
loop.run_until_complete(run())

OverflowError: date value out of range

Bắt đầu với asyncpg/pgproto/./codecs/datetime.pyx tại timestamptz_decode, sau đó tái hiện lỗi bằng truy vấn Python được cung cấp đối với PostgreSQL. Theo dõi cách timestamp được báo cáo được giải mã và thêm coverage cho trường hợp này nếu repository có vị trí test phù hợp. Hoàn thành có nghĩa là truy vấn trả về timestamp mà không xảy ra OverflowError.
