Hi,given this setup:create table part2 ( a int, list varchar(10) ) partition by hash (a);create table part2_1 partition of part2 FOR VALUES WITH (MODULUS 3, REMAINDER 0);create table part2_2 partition of part2 FOR VALUES WITH (MODULUS 3, REMAINDER 1);create table part2_3 partition of part2 FOR VALUES WITH (MODULUS 3, REMAINDER 2);insert into part2 (a,list) values (1,'aaa');insert into part2 (a,list) values (2,'bbb');insert into part2 (a,list) values (3,'ccc');... it is possible to insert rows like this which will always go to the first partition:insert into part2 (a,list) values (null,'ddd');insert into part2 (a,list) values (null,'eee');select * from part2_1;a | list
---+------
2 | bbb
| ddd
| eee
(3 rows)I suppose this is intended but I could not find anything in the documentation about that. Can someone please clarify the logic behind that?
>> The calculated hash value for the null value will be zero, therefore, it will fall to the partition having remainder zero.
Thank you, Amul
