Kind of. The indicators are set in the Main functions after
InitPostmasterChild and some other setup. In my little bit of digging

It kind of seemed like it, but I noticed the small differences in
requirements, which made me a bit hesitant. I'll go ahead and see what
I can do and submit the patch for consideration.
