FAQ, statement_cache_size=0...

还没有人认领这个 Issue。

I have done a create_pool, passing the argument 'statement_cache_size=0"; I am STILL _periodically_ getting the DuplicatePreparedStatement error on statements prepared from a connection acquired from that pool.

Any other options? All other facilities appear to work reliably in your driver except this critically important prepared statement facility.

Running your latest driver, postgres 12; application is running in the context of a uwsgi server app. Connecting via a socket file (in /var/run...) to postgres...

首先，在通过 Unix socket 连接 PostgreSQL 12 的 uwsgi 应用程序中，复现 statement_cache_size=0 的 create_pool 配置。调查从池中获取的连接在什么情况下仍会产生 DuplicatePreparedStatement 错误；当复现出所报告的周期性错误，并确定其原因或可靠的解决方案时，即表示完成。
