Sure, I was just a bit scared because of production servers with
standard_conforming_string ON.
One interesting thing in this area is that I found very usefull to
turn this param ON for windows path. (so perhaps we will have more
testing coming from windows users than others ...)

I agree and I don't care this parameter is really on or off by
default. I just wanted to be sure it is sane enough to use it.

Sounds good.
