Schema changes should propagate to inheritance children #6
Description
When an Iceberg table is in an inheritance hierarchy, parent schema changes are not applied into the Iceberg metadata of the children.
Heap tables:
create table par (id bigint, value text);
create table child1 (id bigint, value text);
create table child2 (id bigint, value text);
alter table child1 inherit par;
alter table child2 inherit par;
alter table par add column z int;
select * from par;
┌────┬───────┬───┐
│ id │ value │ z │
├────┼───────┼───┤
└────┴───────┴───┘
