Agreed. Very interesting. I think we should also "recommend" our
users to move forward. I don't see someone willing to upgrade to
PostgreSQL 10 but not willing to update the JRE (it's either both or
none, and if it is none, they are well served with existing drivers).

So what do we do? I can still develop SCRAM for either version of
Java (and while I have already expressed my preference, I will do it
even for Java6, if that's the decision) :) I'm not a committer, so
committers: please let me know what would be the "official" final
decision. Thanks,

Álvaro
