While this could be beneficial from the "one jar to rule them all"
standpoint, I think this is too much hassle.

Yep.

I think we could just have two jars

psql-debug.jar  -- provide very loud logging if Statements and Connections
are not explicitly closed, which can be used for development and debugging.
psql-prod.jar -- without finalize() calls for integration, performance testing and
production

Deliberately relying on the current behavior is just bogus and I guess
no one will know if they accidentally rely on it :-)

Besides that: tools like Findbugs or IntelliJ IDEA warn you when Statements
are not closed as they consider that a leak.
