Description

I am using asyncpg to query an postgres rds cluster. In my app I use asyncpg connection pools to aquire a connection and query the DB. I recently stood up an RDS Proxy in front of my RDS Cluster and I see almost 100% pinning because of the reset query used by asyncpg. I keep seeing the below message in my RDS Proxy logs for the pinned connections.

Consider moving session configuration to the proxy's initialization query. Digest: "select pg_advisory_unlock_all(); close all; unlisten *; reset all;".

Has anyone else run into connection pinning in RDS Proxy? I feel like the correct approach is not what is mentioned in the logs.

Thanks in advance :)

Research direction

No files, tests, or entry points are mentioned. Start by reviewing asyncpg's connection-pool reset behavior alongside the RDS Proxy pinning log, then establish whether the reported reset query can be changed without breaking connection cleanup and verify the resulting pinning behavior.
