Hello sh.itjust.works community,
It’s been a while since my last update, and I owe you all a more detailed one soon. However, today I’m here to give you a heads-up about the upcoming upgrade.
Over the next 7 days, I’ll be upgrading the instance to v19.5. While this update doesn’t strictly require it, I’ve decided to take this opportunity to upgrade our Postgres database from version 15 to 16 as well. This process can be time-consuming and have take up to 2 hours to complete on other instance.
I’m optimistic that we’ll complete it in less time, but to err on the side of caution, I’ve scheduled the maintenance window for 120 minutes.
To minimize downtime, I’ve split the upgrade into two phases: Phase one will cover the database update, and Phase two will handle the Lemmy code upgrade.
Note: If the database upgrade is completed in under 60 minutes, I’ll proceed with the Lemmy code upgrade during the same maintenance window.
Here’s the tentative timeline:
| Task | Date | Expected Downtime |
|---|---|---|
| Upgrade of Postgres Database | Friday September 20 2024 @ 8:00PM ET | 60-120 Minutes |
| Upgrade to V19.5 |
During these two planned events those who want to provide moral support or who want to get periodic updates are more than welcome to join us on our matrix channel
edit: 9:23EDT - Hey all, the database and lemmy codebase has been upgraded to v19.5. The database upgrade took a lot less time than expected so I went right into upgrading the codebase. A whole bunch of background tasks are still running which might make your experience slower than usual. Things should be back to normal in the next couple of hours.
A few images which were previously federated seem to have disappeared. Any idea what happened to them?

This is odd. I did not upgrade pictrs (the service responsible for image hosting). There may have been an error for some specific tables rows during the database migrates. Another possibility could have been an error during the schema update that I believe the new version had to go through.
Would you be able to DM me links to other posts that you come across with broken images? I will look to see if I can identify any common trends that could tell us more.
Thank you
I can’t find any at the moment, and my original example seems to have resolved itself. If I come across any others, I’ll send them your way.
