Hi, thank you very much for your advice, I have attached the log. As proposed I've replaced the original file and restarted the server, yet unfortunately I'm still unable to get any results for any simple statement (ie SELECT * FROM table). In my understanding the obj_id is anyhow faulty since there are no negative values of attrelid in pg_attribute. Running the statement primary_keys.sql with the proper value returns the requested row (table.id).
