Well, most of the settings that would be sensible for this are used in
cost estimates that are basically per-table or per-index, so I don't
think it's a huge problem in practice. But I should clarify my comment:
the set of GUCs used this way must not be wired into the catalog
structure. I think that the code will only pay attention to certain
GUCs that are valid in-context, but we shouldn't have to redesign the
catalog each time we add one.
