This seems like a pretty awful idea, mainly because there's no way
to have such a GUC mean anything on non-glibc platforms, which is
going to cause confusion or worse.
Aren't these same settings controllable via environment variables?
I could see adding some docs suggesting that you set thus-and-such
values in the postmaster's startup script. Admittedly, the confusion
argument is perhaps still raisable; but we have a similar docs section
discussing controlling Linux OOM behavior, and I've not heard much
complaints about that.
