I should post that in the general section but I am confused by the sentence "A parent partition is always going to have a lower relid than its children"

In fact, I want to be sure I can say to the developers they will always be able to create tables and partitions in any order :
create table child1(c1 int, c2 int);
create table midparent1(c1 int, c2 int) partition by list(c2);
alter table midparent1 attach partition child1 for values in (1);
create table child2 partition of midparent1 for values in (2);
create table topparent(c1 int, c2 int) partition by list(c1);
alter table topparent attach partition midparent1 for values in (1);
select relname, relkind, oid from pg_class where relname in ('topparent', 'midparent1', 'child1', 'child2') order by oid asc;
relname | relkind | oid ------------+---------+-------- child1 | r | 123989 midparent1 | p | 123992 child2 | r | 123995 topparent | p | 123998 (4 lignes)
