inherited tables failure
We have two tables inherited one from the other one. If you try to insert from the parent into the child by an "INSERT INTO" statement then the record is inserted into the child but into the parent too! Therefore in the parent duplicated rows appear.
The other bug is if you delete a row from the parent then it erases from the child too. see the illustration below.
create table try (col1 int4);
create table try1 () inherits (try);
insert into try (col1) values (15);
select * from try1; --> you get 0 row
select * from try; --->you get 1 row
insert into try1 select * from try; --> the answer is 1 row is inserted into try1
select * from try1; --> you get 1 row
select * from try; --->you get 2 row !!!!!!!!!!! <-That's wrong
delete from try;
select * from try1; --> you get 0 row !!!!!!!!!!! <-That's wrong
select * from try; --->you get 0 row
