Konstantin Tretyakov 8722fb84a6 Fix the "greatest" example. ...

The current example code does not pass `**kw` down to the `compiler.process` calls, thus the example does not work when invoked with, `literal_binds=True`.

Besides, the calls to `process` each argument twice are wasteful, and reusing the built-in `case` expression instead of hard-coding the SQL statements is slightly nicer overall, isn't it?
