Hm, works for me:

regression=# create table tab1 (index serial primary key, data text);
NOTICE: CREATE TABLE will create implicit sequence "tab1_index_seq" for "serial" column "tab1.index"
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "tab1_pkey" for table "tab1"
CREATE TABLE
regression=# create rule r as on update to tab1 where old.index = new.index do instead nothing;
CREATE RULE
regression=# select version();
version
