HASH partitioning not working properly

   After seeing the below, I feel partitioning is not working properly or it maybe case that my understanding is wrong.  Can somebody explain me what is happening?

postgres=# create table busbar_version (objectid int, ver_id int) partition by hash(ver_id);
CREATE TABLE
postgres=# CREATE TABLE busbar_version0 PARTITION OF busbar_version FOR VALUES WITH (MODULUS 10, REMAINDER 0);
CREATE TABLE
postgres=# CREATE TABLE busbar_version5 PARTITION OF busbar_version FOR VALUES WITH (MODULUS 10, REMAINDER 5);
CREATE TABLE
postgres=# CREATE TABLE busbar_version6 PARTITION OF busbar_version FOR VALUES WITH (MODULUS 10, REMAINDER 6);
CREATE TABLE
postgres=# CREATE TABLE busbar_version7 PARTITION OF busbar_version FOR VALUES WITH (MODULUS 10, REMAINDER 7);
CREATE TABLE
