And what about the application changing it after the fact? One idea would be to have a log line designed specifically to be printed once at connection start (if not log_connections) and then once immediately after it changes. Am I the only one for whom this sounds like overengineering? I think the idea is nice, but I'm not sure about feasibility. I further think that the idea in the OP is sound enough. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
