I'm not Robert, but I still have an opinion here, and that it's that this
feature would at best be an attractive nuisance. If you need compression
on a database session, it probably means that the connection is over the
open internet, which means that you need encryption even more. And we
know that compression and encryption do not play well together. The
reason compression was taken out of the latest TLS standards is not that
they wouldn't have liked to have it, nor that applying compression in a
separate code layer would be any safer. I fear offering this would
merely lead people to build CVE-worthy setups.
