This is as expected. Once the index is created on the partitioned set of tables, the index on the *root* table will be ON ONLY that table; the child tables appear separately:

xof=# create table t (i bigint) partition by range(i);
CREATE TABLE
xof=# create table t001 partition of t for values from (1) to (2);
CREATE TABLE
xof=# create index on t(i);
CREATE INDEX
xof=# select * from pg_indexes where tablename = 't';
schemaname | tablename | indexname | tablespace | indexdef
------------+-----------+-----------+------------+-------------------------------------------------------
public | t | t_i_idx | | CREATE INDEX t_i_idx ON ONLY public.t USING btree (i)
(1 row)

xof=# select * from pg_indexes where tablename = 't001';
schemaname | tablename | indexname | tablespace | indexdef
------------+-----------+------------+------------+--------------------------------------------------------
public | t001 | t001_i_idx | | CREATE INDEX t001_i_idx ON public.t001 USING btree (i)
(1 row)
