that's a fair point (like I expect debian to provide 9.0 as a backport)
though the packages could just change the default for that backport.
The precedence for that is standard_conforming_strings which we now have
for a while(since 8.2 iirc) - though I don't think we have a firm plan
on when we are actually going to turn it on...
Not sure if we really need to wait 4 major releases to allow driver
developers to adapt...
So one idea would be to turn it off for 9.1 and enable that and scs for
9.1 and try to get driver developers attention early in the release cycle.
