Hi,

Do you have multiple task table created in your database? 

Can you share the output of \d+ task_history?

Can something explain why something like the following could happen?

 

INSERT INTO task_history (task_id, user_id, task_date)

SELECT task_id, user_id, task_date

FROM task

WHERE task_id IN (1, 2, 3);

 

ERROR: insert or update on table "task_history" violates foreign key constraint "fk_task_history_task_id"

  Detail: Key (task_id)=(1) is not present in table "task".

 

Thanks,

Manfred
