* **asyncpg version**: 0.22.0
* **PostgreSQL version**: 12
* **Do you use a PostgreSQL SaaS? If so, which? Can you reproduce
the issue with a local PostgreSQL install?**: AWS Aurora . Cannot reproduce with a local PostgreSQL.
* **Python version**: v3.7.6+
* **Platform**:
* **Do you use pgbouncer?**: No
* **Did you install asyncpg with pip?**: Yes
* **If you built asyncpg locally, which version of Cython did you use?**: N/A
* **Can the issue be reproduced under both asyncio and
[uvloop](https://github.com/magicstack/uvloop)?**: just uvloop

It seems like asyncpg's connection pooler is not gracefully terminating connections. This seems to happen only with AWS Aurora version, but not the locally installed Postgres version.

Aurora Postgre has `idle_in_transaction_session_timeout` set to `86400000`.

Here is the code to help reproduce this issue. .

```
from sanic import Sanic, Blueprint
from sanic.exceptions import NotFound
from sanic.response import json
from sanic.handlers import ErrorHandler
import asyncpg

app = Sanic(name="asyncpg-errors")
bp = Blueprint("info", url_prefix="/info")

DB_CONFIG = {
'host':,
'user': ,
'password': ,
'port': 5432,
'database': 'postgres'
}

def log_listener(connection, message):
print(message)

@app.listener('before_server_start')
async def init(app, loop):
app.pool = await asyncpg.create_pool(
**DB_CONFIG, loop=loop,
max_size=10, max_inactive_connection_lifetime=1
)

@bp.route('/', methods=['GET'])
async def info(request):
async with request.app.pool.acquire() as conn:
conn.add_log_listener(log_listener)
d = await conn.fetchrow('''SELECT * FROM mmrtest limit 1''')
return json(dict(d))

group = Blueprint.group(bp)
app.blueprint(group)

app.run(port=9091, access_log=True, debug=True)

```

```

Inizia con la riproduzione Sanic fornita, concentrandoti su asyncpg.create_pool, max_inactive_connection_lifetime e sul percorso di acquisizione/rilascio della connessione. Eseguila su AWS Aurora e confronta il suo comportamento con PostgreSQL locale sotto uvloop. Il lavoro è completato quando il comportamento di reimpostazione della connessione è spiegato ed è documentata una correzione verificata o un prossimo passo con ambito strettamente definito.
