Thanks. Reproduced with
create table main (a int primary key);
create table part (a int references main) partition by range (a);
create table part1 partition of part for values from (1) to (100);
alter table part detach partition part1;
alter table part attach partition part1 for values from (1) to (100);
Looking into it.
