Yeah, at this point we will probably need a discussion and explanation of the protocol behavior this is adding, such as how to negotiate different compression settings.
Unrelatedly, I suggest skipping the addition of -Z options to various client-side tools. This is unnecessary, since generic connection options can already be specified via -d typically, and it creates confusion because -Z is already used to specify output compression by some programs.
As the maintainer of the JDBC driver I would think we would also like to leverage this as well.
There are a few other drivers that implement the protocol as well and I'm sure they would want in as well.
I haven't looked at the patch but if we get to the point of negotiating compression please let me know.
