I don't see how to do it at compile time without getting the
preprocessor involved. What do you think about this version?
[ATTNUM] = {
AttributeRelationId,
AttributeRelidNumIndexId,
KEY(Anum_pg_attribute_attrelid,
Anum_pg_attribute_attnum),
128
},

It fails very early in testing if you do that. Admittedly, the
assertion is hard to understand, but if I add a new assertion close to
the cause with a new comment to say what you did wrong, I think that
should be good enough?
