Well, what if we indeed release 9.5.x just to note that "it is at
least helloworld-compatible with backend 9.5"?
I guess as long as pgjdbc's versions are "close" to backend's
versions, users would be confused if those are compatible.
So it looks we either have to release pgjdbc 9.5.x, or release
something like 42.x.y
Any thoughts?
