FWIW, it's likely that the next version of TLS (version 1.3, see[1])
will no longer support compression at all. The concensus appears to be
that this is the wrong level to be applying compression.

Since the only way to get compression currently in Postgres is via TLS,
perhaps we should look at supporting compression natively in future
protocol versions.

It will take a while for TLS 1.3 to be deployed so there's time, but
PostgreSQL protocol revisions go at a similar pace.

Have a nice day,
