I'm still a bit befuddled by this interface.
libpq_compression=gzip:compress=off looks a lot like it's saying "do
it, except don't". I guess that you're using "compress" and
"decompress" to distinguish the two directions - i.e. server to client
and client to server - but of course in both directions the sender
compresses and the receiver decompresses, so I don't find that very
clear.

I wonder if we could use "upstream" and "downstream" to be clearer? Or
some other terminology?
