PgBouncer：关闭因为：客户端关闭请求和关闭因为：不干净的服务器

问题描述

虽然我的网络应用程序运行良好，并且数据写入数据库没有问题。我查看了 PgBouncer 的日志，它显示了大量的

我想知道，这是 PgBouncer 的正常情况吗？

我只是在数据库上执行正常的读/写，并进行了适当的连接清理。

conn = None
cursor = None

try:        
    conn = psycopg2.connect(constants.POSTGRES_CONNECTION_STRING)        
    cursor = conn.cursor()
    
    ...
    
    conn.commit()
except Exception as e:
    ...
finally:
    if cursor is not None:
        cursor.close()
    
    if conn is not None:
        conn.close()

我在 docker 中的设置也非常简单。

Dockerfile

FROM edoburu/pgbouncer:1.15.0

copY pgbouncer.ini /etc/pgbouncer/
copY auth_file /etc/pgbouncer/

pgbouncer.ini

listen_addr = 0.0.0.0
auth_file = /etc/pgbouncer/auth_file
auth_type = md5
ignore_startup_parameters = extra_float_digits
# Log settings

你知道为什么我收到大量的日志消息吗

• 关闭原因：客户关闭请求
• 关闭原因：服务器不干净

有任何顾虑吗？

谢谢。
