I agree that network debug trace logs would be useful for users not knowledgeable
of postgres internals, so I understand the value of the feature,
as long as only necessary/digestible information is outputted.
I'll also check the patch later.
For Andres, I haven't looked into tcpdump yet, but I'd like to ask whether
or not the decrypted output to .pcap (if implemented) may be useful to
application users. What could be the limitations?
Could you explain a bit further on the idea?
