For a) I think volatile function issue can be resolved by using hidden columns in the heap itself. This will create a duplication of data, but since the index will get created on it, it will always point to the right heap tuple For b) We are already suffering with this issue in any index lookups, index based updates/deletes, unique constraints, referential integrity maintenance etc. So hopefully one day we can extend this list to include more :)) Gokul.
