OK, I've started a new thread for this issue at [1].

If there are many GUCs that behave incorrectly during bootstrap,
a general mechanism like that might be worth considering. But if
only a few GUCs are affected, as I believe is the case,
then such a mechanism may be overkill.

In that case, IMO it should be sufficient to disable the problematic
GUCs individually, for example by calling SetConfigOption(..., PGC_S_OVERRIDE).
