I don't think so. Here's an example from a 9.2.0.3 database: SQL> create table t (v varchar2 (10), d date) ; Table créée.
SQL> create bitmap index bit1 on t (v) ; Index créé.
SQL> alter table t add (constraint t_pk primary key (v)) ; alter table t add (constraint t_pk primary key (v)) *
ERREUR à la ligne 1 :
ORA-01408: such column list already indexed
