We are using Discourse with an external database instead of the integrated, Docker-based Postgres. We recently had to upgrade our Postgres cluster to 14, thus the Discourse backup keeps failing.

Is there any way to upgrade the
postgresql-client 13.5-1.pgdg100+1 of the container to version 14?
We upgrade Postgres versions every two releases, because it takes a tremendous amount of engineering resources to upgrade the database. We are currently on Postgres 13 so we’ll upgrade to Postgres 15.1 when that is released (the bugfix point release).
I do understand, but thanks for pointing out the upgrade policy - really good to know. We are aware of engineering resources regarding the DB. I love Postgres, but upgrading our cluster usually turns us to be devout Catholics - many prayers beforehand, but still a lot of blood, sweat and tears.
You should be able to manually install the required
postgresql-client by adding the appropriate
apt-get commands to your
Would this cause any depency issues with Ruby gems of the application itself? As far as I understand adding
apt install as a hook requires a
launcher rebuild app, right? If so, I would skip this for another dreaded upgrade as described here in another topic of mine , we face massive problems of rebuilding the app inside China. That’s the reason why I would like to clarify if just entering the app and then manually installing it via apt would do the trick.
I suggest you test it on a staging site before doing anything in production, but I think there won’t be any issues with Ruby gems. Installing it in the running container should work as well.
So you will create the script next year in 2023 ? PostgreSQL: Versioning Policy
Should I open a new ticket for Backup failure ?
??? it takes a tremendous amount of engineering resources ???
It seems that these simple lines of commands to update the postgresql database from 13.5 to 14.1 solve the backup problem… Cheers
./launcher enter app
sudo apt-get install postgresql
to officially support it, yes.
