Because those flags are set by the child processes too, cf
MarkPostmasterChildActive and MarkPostmasterChildInactive.

I am, but I'm not inclined to push this immediately before a wrap.
If we intend to wrap 15.0 on Monday then I'll wait till after that.
OTOH, if we slip that a week, I'd be okay with pushing in the
next day or two.
