So, nobody's actually spoken against this change.  I think we should
go forward with it, for the reasons I gave at the top of the thread
and because "if not now, when?".  I have little doubt that if there
is anyone still running with standard_conforming_strings = off, they
aren't going to change until forced to.  So unless we want to live
with the potential security hazard forever, we're going to have to
make a breaking change sometime.
