I think this is proof that it's not my personal environment, nor something intrinsic in the codebase, but definitely something in the standard EDB installer.

No, you're on the wrong track. As I reported earlier, I have reproduced
this issue with a vanilla build which has no installer involvement
whatsoever.

I'm pretty sure the reason you are not seeing this with the 2ndQuadrant
installer is quite simple: it wasn't build with NLS support.

Let me repeat what I said earlier. I will get to the bottom of this.
Please be patient and stop running after red herrings.
