Baldvin posted this greatly simplified test case, which also
crashes the server without even using PL/pgSQL on pgsql-sql.
-- Hi Kevin, and everyone!
--
-- I don't think that I only found a minor bug compared to
-- the other you wrote in your last letter: the backend crash
-- is caused by the same CHECK constraint in the child table.
--
-- However, for you without time to analyzing Kevin's huge
-- scheme, here is the very simplified, crash-causing script.
--
------------------------------------
drop table child;
drop table ancestor;
create table ancestor (
node_id int4,
a int4
);
create table child (
b int4 NOT NULL DEFAULT 0 ,
c int4 not null default 3,
CHECK ( child.b = 0 OR child.b = 1 )
) inherits (ancestor);
insert into ancestor values (3,4);
insert into child (node_id, a, b) values (5,6,1);
update ancestor set a=8 where node_id=5;
---------------------------------
--
-- I am hunting it, but I have to learn all what this query-executing
-- about, so probably it takes uncomparable longer for me than for
-- a developer.
--
-- Regards,
-- Baldvin
