Seems harder than it sounds ... because if the user turns off
log_connections then it's not longer in the log. 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.
