another bug. I will dig later, just want to share it first. minimum producer: drop table if exists pp1,cc1, cc2,cc3; create table pp1 (f1 int ); create table cc1 () inherits (pp1); create table cc2() inherits(pp1,cc1); create table cc3() inherits(pp1,cc1,cc2);
alter table pp1 alter f1 set not null; ERROR: tuple already updated by self
