Not related to DETACH PARTITION, but I found a bug in ATTACH PARTITION.
Here are the steps to reproduce the issue:
create table tpart(i int, j int) partition by range(i);
create table tpart_1(like tpart);
create table tpart_2(like tpart);
create table tpart_default(like tpart);alter table tpart attach partition tpart_1 for values from(0) to (100);
alter table tpart attach partition tpart_default default;insert into tpart_2 values(110,110),(120,120),(150,150);1: begin;
1: alter table tpart attach partition tpart_2 for values from(100) to (200);
2: begin;
-- insert will be blocked by ALTER TABLE ATTACH PARTITION
2: insert into tpart values (110,110),(120,120),(150,150);
1: end;
2: select * from tpart_default;
2: end;
After that the partition tpart_default contains (110,110),(120,120),(150,150)
inserted in session 2, which obviously violates the partition constraint.
