Getting this error a lot in Sidekiq (Retries and Dead lists):
Jobs::HandledExceptionWrapper: Wrapped ActiveRecord::RangeError: PG::NumericValueOutOfRange: ERROR: integer out of range
The jobs I’ve noticed this identical error for are:
Jobs::PostAlert
Jobs::ProcessPost
Jobs::NotifyCategoryChange
This was discussed a bit in the past here: Feedback on the new Review Queue - #250 by markersocial
Can you please run:
cd /var/discourse/
./launcher enter app
su postgres
psql
\x
\connect discourse
SELECT id FROM notifications ORDER BY 1 DESC LIMIT 1;
\q
exit
Thanks @Falco, I just ran it now. Here is the result:
-[ RECORD 1 ]--
id | 2147483496
Okay, so it’s the famous integer max problem. We need to move to bigint to fix this. I will take a look into this.
For now your workaround is to run:
cd /var/discourse/
./launcher enter app
su postgres
psql
\x
\connect discourse
ALTER TABLE notifications ALTER COLUMN id SET DATA TYPE bigint
\q
exit
This is the default for new installs but old installs have the wrong data type.
Running the workaround may be hard cause it will block the table, you many need to shed your web load first.
Thanks @Falco & @sam - appreciate it 
Regarding the workaround, this should be relatively safe to do? Not worried about down time, just breaking something.
It’s using the standard app.yml single container. For shedding the web load, do you think using read-only mode and running ./launcher stop app, ./launcher start app prior to doing the workaround probably suffice?
It will not break anything, worst case is that it will just be “stuck” for a very long time.
Thanks Sam, I did the workaround. Though, did not get any feedback upon inputting:
ALTER TABLE notifications ALTER COLUMN id SET DATA TYPE bigint
Not sure if it’s still processing perhaps. Currently getting the same error (in the /sidekiq dead list, for last retry ‘just now’ jobs) for:
Jobs::PostAlert
Jobs::ProcessPost
Jobs::NotifyCategoryChange
Looks like you need to run in with post_id column as well
Thanks!
Just to be sure, does this look correct?
ALTER TABLE notifications ALTER COLUMN post_id SET DATA TYPE bigint
Yes that should be safe, once we add an official migration it will allow for it
Perfect, thanks
I ran that (no confirmation/feedback received, like the previous one). Forum didn’t slow down, so not sure if it worked. Getting the same errors currently.
Maybe it would be best if I wait for the official migration.
Yeah looks like this is in the post_alerts table, we need to sweep through many tables
Curious where you are on this issue now? Did the errors stop?
Originally we were thinking of making some official migration here, but the risk far outweighs the benefit. We find it exceedingly rare to come across DBs with more than 2,147,483,647 posts. 2.1 billion is a real big number.
The downside of increasing the sized everywhere are that storage requirements go up.
Where we are now is that we are considering adding a rake task that “makes space” if you are in an outlier case where you have tables in Discourse that containe 2 billion rows (or had 2 billion rows of churn)
Thanks for the follow up @sam
I just upgraded to 2.8.0.beta6 and still getting the integer out of range errors.
I think that it’s just the notifications that has got to a massive number, which is a bit more realistic to reach the limit compared to number of posts. A lot of large topics with many replies, likes etc. from different users can result in quite a lot of notifications.
A rake task sounds fantastic
Je sais que c’est un vieux fil de discussion –
Nous venons de rencontrer ce problème dans notre configuration également (devforum.roblox.com) ! Nous utilisons la version v2.8.9, mais nous passerons bientôt à la version 3.0.1.
Nous avons remarqué que quelque chose n’allait pas lorsque les utilisateurs ont commencé à voir des erreurs 403/500 en essayant d’aimer/ne plus aimer des publications.
Ensuite, je suis tombé sur ce fil de discussion et j’ai vérifié notre table de notifications :
=> SELECT id FROM notifications ORDER BY 1 DESC LIMIT 1;
id
------------
2147483647
(1 row)
@sam La solution de contournement ci-dessus est-elle toujours la meilleure suggestion, ou une tâche rake a-t-elle été davantage prise en compte depuis septembre 2021 ?
Plus d’informations –
Après avoir modifié la colonne notifications.id, je rencontre un problème distinct avec le job Jobs::PostAlert
Job exception: 2147498514 est hors de portée pour ActiveModel::Type::Integer avec une limite de 4 octets
Peut-être y a-t-il une autre table/colonne que j’ai manquée ? Ou quelque part dans Ruby qui s’attend toujours au type de données entier ?

Oui, cela reste le seul correctif ici. Je crains de le changer dans le cœur, mais je suppose que cela continuera à se produire sur les forums gigantesques si nous ne corrigeons pas cela.
Le revers de la médaille est une augmentation du stockage.
Savez-vous s’il existe des utilisations dans le service post_actions (ou quelque part dans le processus de notification) qui pourraient encore attendre des entiers après l’exécution de ALTER ?
Nous constatons des erreurs 5xx sur les appels like/unlike vers /post_actions avec la réponse
{"errors":["The requested URL or resource could not be found."],"error_type":"not_found"}
De plus, certaines tâches échouent autour des notifications (Jobs::BookmarkReminderNotifications, Jobs::GrantAnniversaryBadges, Jobs::PostAlert).
J’ai ajouté la trace de la pile pour PostAlert dans mon message précédent ; il semble y avoir un problème lancé pour une limite d’entier par consolidate_or_create dans notification.rb.
Pour notre utilisation, l’augmentation du stockage n’est pas une préoccupation majeure si nous pouvons restaurer la fonctionnalité 
Essayez peut-être de redémarrer votre conteneur, il pourrait y avoir des éléments mis en cache en mémoire.
