Prepared statements with connection pool

Hi, I have troubles using prepared statements with connection pool. AFAIK you have to setup prepared statement for each connection you are using (https://www.postgresql.org/docs/9.3/static/sql-prepare.html):

Prepared statements only last for the duration of the current database session. When the session ends, the prepared statement is forgotten, so it must be recreated before being used again. This also means that a single prepared statement cannot be used by multiple simultaneous database clients; however, each client can create their own prepared statement to use.

So what is preferred way to work with prepared statements with connection pool? Should I, after connect, prepare statements for each connection of connection pool (how to iterate them?)? Should I use setup keyword of create_pool? But that is called each time acquire and we do not get references to statements easily. How to handle statement references? Dict of connection: statements?
Is there a way to do it with asyncpg? Could you send me an code example how to do it or even better add it to documentation?

首先阅读连接池的 create_pool API 及其设置回调，然后查看 issue 中描述的 prepared statement 行为。一个有用的成果是提供一个有文档说明的 asyncpg 示例，解释如何在池化连接中处理 prepared statement，包括如何管理 statement 引用。
