I haven't used this table myself, it's coming from SER branch, but I guess the unique constraint is for being sure there are no duplicated values for the same did/name tuple, but more records with same did and name.
lookup_domain() adds attributes associated with did to AVPs. Sure there can be more than one AVP with the same name. Therefore I suggest removing name and value from the index.
