PostgreSQL version: 8.3.3
Operating system: Windows XP
Description: Inheritance fails on column suppression
Details:
Hello,
I use Postgresql on Windows XP 8.3.3.
I have created 2 schema, and the tables of the second one inherits the
tables of the first one :
CREATE schema test1;
CREATE schema test2;
CREATE TABLE test1.point (code char(16), test1 char(2), test2 char(3));
CREATE TABLE test2.point (code2 char(16)) INHERITS (test1.point);
Then, I remove th inheritance link by performing an ALTER command :
ALTER TABLE test2.point NO INHERIT test1.point;
And then, I restablish the inheritance :
ALTER TABLE test2.point INHERIT test1.point;
The problem is that, if now I drop a column from the parent table, the
column remains in the child table, whereas the inheritance is established :
ALTER TABLE test1.point DROP COLUMN test2 CASCADE;
The column "test2" remains in "test2.point" table.
According to the documentation, this should not be the case.
Regards,
C. Duprez
