Announce it as a change for 9.1 NOW, and then it will be whoever's
fault if they aren't paying attention.  Plenty of time to fix it
if it's announced now.

Also, as long as the config option is there, they can always flip it
back, which makes it MUCH lower overhead than the casting change was.
Overall, I don't think this change is nearly as severe as the cast
change in 8.3, and I don't feel it warrants the same eggshell walking.
When the decision is made to remove the standard_conforming_string
config option altogether ... that'll be a different story!
