Primary key with oid + name : error, which solution ?

I create two table repertory and person. And i have an error :


> CREATE TABLE repertory (name_rep name, attribut text[], PRIMARY
KEY(name_rep));

> CREATE TABLE person (nam_rep repertory, name_pers text, url text,
eadr text, tel text, attribut text[], PRIMARY KEY(name_pers,nam_rep));


NOTICE:  CREATE TABLE/PRIMARY KEY will create implicit index
'person_pkey' for table 'person'

ERROR:  DefineIndex: type repertory has no default operator class


which solution for this problem ?
