Ignore/reconnect for closed connection in pool - postgresql

Question

I have some problem with pool.acquire() and closed connection in pool.
Setting on PG Server set connection timeout to 120 second. When i use pool.acquire() it is raise error because connection is closed:
Sleep 150
Traceback (most recent call last):

and code
import asyncio

dsn = 'dbname=dbname user=user password=password host=127.0.0.1'
async def test_select():
async with aiopg.create_pool(dsn) as pool:
print("Sleep 150")
await asyncio.sleep(150)
async with pool.acquire() as conn:
async with conn.cursor() as cur:
await cur.execute("SELECT 1")
ret = []
async for row in cur:
ret.append(row)
assert ret == [(1,)]
print("ALL DONE")
loop = asyncio.get_event_loop()
loop.run_until_complete(test_select())
How to solve this problem.
Thanks!
