Glad to see progress being made! Well written blog!
If I may, one thing that has been a constant troublemaker for us - running primarily on AWS - is timeouts. I would love to see a fundamental implementation of timeouts at the connection level, regardless of activity - e.g. in the middle of a query, between queries, etc.. If the connection hangs (because the server disappeared or failed over) or does not respond (particularly in the weird cases like when the destination IP just vanishes and the tcp timeout kicks in) - I'd like to know about it within a reasonable time and be able to react to that.
I have started working on psycopg3. Database communication is up and running, sync and asyncio, and now I'm busy with the definition of the adaptation layer.
