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
Sei que este é um tópico antigo –
Acabamos de encontrar esse problema em nossa configuração também (devforum.roblox.com)! Estamos executando a v2.8.9, mas atualizaremos para a 3.0.1 em breve.
Notamos que algo estava errado quando os usuários começaram a ver 403/500 ao tentar curtir/descurtir posts.
Então me deparei com este tópico e verifiquei nossa tabela de notificações:
=> SELECT id FROM notifications ORDER BY 1 DESC LIMIT 1;
id
------------
2147483647
(1 row)
@sam A solução alternativa acima ainda é a melhor sugestão, ou foi dada mais consideração a uma tarefa rake desde setembro de 2021?
Mais informações –
Após alterar a coluna notifications.id, estou vendo um problema separado do job Jobs::PostAlert
Job exception: 2147498514 está fora do intervalo para ActiveModel::Type::Integer com limite de 4 bytes
Talvez haja outra tabela/coluna que eu esteja perdendo? Ou em algum lugar no ruby que ainda esteja esperando o tipo de dado inteiro?

Sim, esta continua sendo a única solução alternativa aqui. Preocupo-me em alterá-la no núcleo, mas acho que isso continuará acontecendo em fóruns gigantescos se não resolvermos isso.
A desvantagem é o aumento do armazenamento.
Você sabe se há algum uso no serviço post_actions (ou em algum lugar no processo de notificação) que ainda possa estar esperando inteiros após a execução do ALTER?
Estamos vendo erros 5xx em chamadas de like/unlike para /post_actions com a resposta
{"errors":["The requested URL or resource could not be found."],"error_type":"not_found"}
Além disso, algumas falhas de jobs em torno de notificações (Jobs::BookmarkReminderNotifications, Jobs::GrantAnniversaryBadges, Jobs::PostAlert).
Adicionei o backtrace para PostAlert em minha mensagem anterior; parece que há um problema sendo lançado para um limite de inteiro por consolidate_or_create em notification.rb.
Para o nosso uso, o aumento do armazenamento não é uma grande preocupação se pudermos restaurar a funcionalidade 
Talvez tente reiniciar seu contêiner, pode haver algo em cache na memória.
