I kind of think this is a lot of unnecessary work. The case that is
problematic is a GUC that's marked GUC_NO_SHOW_ALL but not marked
GUC_NOT_IN_SAMPLE. There aren't any of those, and I don't think there
are likely to be any in future, because it doesn't make a lot of sense.
Why don't we just make a policy against doing that, and enforce it
with an assertion somewhere in GUC initialization?
