Anything like this will involve an API change in the guc stuff, so
that doesn't seem insurmountable.
I like the idea that was mentioned upthread of creating a new "enum"
category for GUC variables, instead of continuing to abuse the rather
inefficient "string" category for the purpose. One reason is that
we then would not be faced with making an incompatible change in
the arguments of DefineCustomStringVariable.
