I tried to connect with psql + client sslmode = require + server requiring ssl with PG17 and trace_connection_negotiation = "on". So "SSLRequest accepted" is logged twice with two different PID. I believe the PID 15553 is psql and 15554 is the PG backend. How do you explain the two connections with SSLRequest? From the log, it seems psql made a connection to itself with SSLRequest and proxied that to Postgres server with a full SSL negotiation. I never saw a log on 15553's connection being closed when I closed the psql process. Does this behavior match what was talked about in the below hacker thread on additional connection?
