Hey, I got the following partitions structure in pg12 beta 3 version : postgres=# \d+ students Partitioned table "public.students" Column | Type | Collation | Nullable | Default | Storage | Stats target | Description --------+---------+-----------+----------+---------+----------+--------------+------------- id | integer | | not null | | plain | | name | text | | | | extended | | class | integer | | | | plain | | Partition key: HASH (id) Indexes: "students_pkey" PRIMARY KEY, btree (id) Foreign-key constraints: "students_class_fkey" FOREIGN KEY (class) REFERENCES class(id) Partitions: students_00 FOR VALUES WITH (modulus 20, remainder 0), students_01 FOR VALUES WITH (modulus 20, remainder 1), students_02 FOR VALUES WITH (modulus 20, remainder 2), students_03 FOR VALUES WITH (modulus 20, remainder 3), students_04 FOR VALUES WITH (modulus 20, remainder 4)
postgres=# insert into students values(20,'a',1); ERROR: no partition of relation "students" found for row DETAIL: Partition key of the failing row contains (id) = (20). I'm trying to insert a few rows but some of them fail on the following error : no partition of relation "sutdents" found for row ... for example : postgres=# insert into students values(20,'a',1); ERROR: no partition of relation "students" found for row DETAIL: Partition key of the failing row contains (id) = (20). postgres=# insert into students values(2,'a',1); ERROR: no partition of relation "students" found for row DETAIL: Partition key of the failing row contains (id) = (2). postgres=# insert into students values(1,'a',1); ERROR: duplicate key value violates unique constraint "students_00_pkey" DETAIL: Key (id)=(1) already exists. postgres=# insert into students values(2,'a',1); ERROR: no partition of relation "students" found for row DETAIL: Partition key of the failing row contains (id) = (2). postgres=# insert into students values(3,'a',1); INSERT 0 1 postgres=# insert into students values(4,'a',1); ERROR: no partition of relation "students" found for row DETAIL: Partition key of the failing row contains (id) = (4). The current content of the table : postgres=# select * from students; id | name | class ----+------+------- 1 | a | 1 3 | a | 1 (2 rows) what am I missing ?
