Hi,
I have created partition table index with some storage_parameter like example given below, I am not able to reset/modify it from partition table. Is this fine.
CREATE TABLE
postgres=# create table part_p partition of part for values from (minvalue) to (maxvalue);
CREATE TABLE
postgres=# create index part_idx on part(a) with (fillfactor = '14');
CREATE INDEX
postgres=# \d part
Table "public.part"
Column | Type | Collation | Nullable | Default
--------+---------+-----------+----------+---------
a | integer | | |
Partition key: RANGE (a)
Indexes:
"part_idx" btree (a) WITH (fillfactor='14')
Number of partitions: 1 (Use \d+ to list them.)
postgres=# \d part_p
Table "public.part_p"
Column | Type | Collation | Nullable | Default
--------+---------+-----------+----------+---------
a | integer | | |
Partition of: part FOR VALUES FROM (MINVALUE) TO (MAXVALUE)
Indexes:
"part_p_a_idx" btree (a) WITH (fillfactor='14')
postgres=# alter index part_idx reset (fillfactor);
ERROR: "part_idx" is not a table, view, materialized view, or index
postgres=# alter index part_p_a_idx reset (fillfactor);
ALTER INDEX
postgres=# \d+ part
Table "public.part"
Column | Type | Collation | Nullable | Default | Storage | Stats target | Description
--------+---------+-----------+----------+---------+---------+--------------+-------------
a | integer | | | | plain | |
Partition key: RANGE (a)
Indexes:
"part_idx" btree (a) WITH (fillfactor='14')
Partitions: part_p FOR VALUES FROM (MINVALUE) TO (MAXVALUE)
postgres=# \d part_p
Table "public.part_p"
Column | Type | Collation | Nullable | Default
--------+---------+-----------+----------+---------
a | integer | | |
Partition of: part FOR VALUES FROM (MINVALUE) TO (MAXVALUE)
Indexes:
"part_p_a_idx" btree (a)

another case where I got error like partition table index is not a index is given below.
postgres=# create table part(a int, constraint part_pk primary key(a)) PARTITION BY RANGE(a);
CREATE TABLE
postgres=# create table part_p1 partition of part for values from (minvalue) to (0);
CREATE TABLE
postgres=# create table part_p2 partition of part for values from (0) to (maxvalue);
CREATE TABLE
postgres=# create EXTENSION if not exists pgstattuple;
CREATE EXTENSION
postgres=# select pgstatindex('part_p1_pkey');
pgstatindex
------------------------------
(3,0,8192,0,0,0,0,0,NaN,NaN)
(1 row)
postgres=# select pgstatindex('part_pk');
ERROR: relation "part_pk" is not a btree index
postgres=#
postgres=# create table part(a int, constraint part_pk primary key(a)) PARTITION BY RANGE(a);
CREATE TABLE
postgres=# create table part_p1 partition of part for values from (minvalue) to (0);
CREATE TABLE
postgres=# create table part_p2 partition of part for values from (0) to (maxvalue);
CREATE TABLE
postgres=# create EXTENSION if not exists pgstattuple;
CREATE EXTENSION
postgres=# select pgstatindex('part_p1_pkey');
pgstatindex
------------------------------
(3,0,8192,0,0,0,0,0,NaN,NaN)
(1 row)
postgres=# select pgstatindex('part_pk');
ERROR: relation "part_pk" is not a btree index
postgres=#
