I don't know how doable this is, but could we use the existing mechanism of
marking an index invalid if it contains an enum type to which a value was
added, and the transaction was rolled back? For the 90% use case, that would
be acceptable, I would expect.
The more I think about this the more I bump up against the fact that
almost anything we do might want to do to ameliorate the situation is
going to be rolled back. The only approach I can think of that doesn't
suffer from this is to abort if an insert/update will affect an index on
a modified enum. i.e. we prevent the possible corruption from happening
in the first place, as we do now, but in a much more fine grained way.
