The script will be useless to you, besides for referencing what to do.
Export, remove pg15, install pg16, import. I think you can streamline with both installed at once as they correctly version. You could also use the in place upgrade. Aptly named: pg_upgradeclusters
But updating to 0.19.4, you do not need to go to pg16… but… you should, because of the benefits!
Congratulations! 👏 Happy B-day and here’s to many more to my across the river friends 🎉
Ps. The video works and is great!
The downvotes you can see (on this post) are from accounts on your instance then. As this post is semi inflammatory it is highly likely to have garnered some downvotes.
Edit: I guess I was wrong regarding the logic of how downvotes work when we block them. As the http request (used too?) return an error when responding to a downvote. I’ll have to look at it again. As the only way it was/is 15, is if:
That awkward moment when you are the person they are talking about when running beta in production!
Should be already fixed. I’ve logged out and in on Jerboa.
We rebuilt the Lemmy container with an extra logging patch. Seems build docs need some work? as that’s the only difference in the past 1-2 days, except for moving to postgres 16…
Thanks for the ping.
I’ve gone back to mainline Lemmy. @[email protected] check now please

See my PR for a new backup script. https://github.com/LemmyNet/lemmy-ansible/pull/210
I’ll get to adding it to the main docs on the weekend.
Tldr, piping your backups via docker is CPU expensive. Directly writing to filesystem in a postgres compatible format with compression is faster and more efficient on the CPU.
My 90GB+ (on filesystem) db compresses to 6GB and takes less than 15 mins.
Been running this since -rc1 & 0.19.1 for the past 13 hours. No issues related to Federation since! just higher CPU load compared to 0.18.x releases.
Thanks for another great release. Suppose I should go fix our ansible ey?
Should be fixed. (It already got merged: https://github.com/LemmyNet/lemmy/pull/4213)
It’s a sad day when something like this happens. Unfortunately with how the Lemmy’s All works it’s possible a huge amount of the initial downvotes are regular people not wanting to see the content, as downvotes are federated. This constituted as part of my original choices for disabling it when I started my instance. We had the gripes people are displaying here and it probably constituted to a lack in Reddthat’s growth potential.
There needs to be work done not only for flairs, which I like the idea of, but for a curated All/Frontpage (per-instance). Too many times I see people unable to find communities or new content that piques their interest. Having to “wade through” All-New to find content might attribute to the current detriment as instead of a general niche they might want to enjoy they are bombarded with things they dislike.
Tough problem to solve in a federated space. Hell… can’t even get every instance to update to 0.18.5 so federated moderation actions happen. If we can’t all decide on a common Lemmy instance version, I doubt we can ask our users to be subjected to not using the tools at their disposal. (up/down/report).
Keep on Keeping on!
Tiff - A fellow admin.
I chose poke bugs. And look where I am now!
Please do not bring your hatred of a few against a whole population. That type of hatred is against Reddthat’s rules.
Please refrain from future comments like that.
If you don’t see create community in the top next to create post, then your home server doesn’t allow users to create community
No. You have to have an account on that server. (And have to use that account regularly as well, otherwise you won’t see reports about your community)
You make posts.
I use Wasabi storage which is more expensive as they have a minimum space allotment but because my servers are in Aus I had issues with backblaze b2 storage and the latency. (I was dealing with 200-300ms in network latency AU -> US + the time that backblaze takes to store the data).
At that time lemmy/pictrs was not as optimised as it is now so it’s much better now.
Backblaze comes out WAY cheaper per-month if you have servers in us/eu, as close to their regions as possible, but they also charge you for API.
As part of an Object Storage / cdn remember you also might have to pay for egress charges as well. Cloudflare is part of the “Bandwidth Alliance” but that isn’t applicable here as pictrs needs to present the images via its own domain, (such as cdn.reddthat.com). So you’ll still want a CDN infront which will mean you will only pay once for the egress instead of everytime everyone loads it.
Reddthat has… looks up 150GB of object storage now.
I would recommend B2 if you are starting out and are in US/EU. Wasabi in all other regions and have a CDN infront. (and don’t mind burning a little cash for peace of mind)
To get it completely free it would need to be:
Because Lemmy does not have a way to have all media served from a different url/subdomain (like a CDN). Your setup will be:
Basically just put cloudflare infront of your vps, and cache everything.
That means if a user uploaded a 10MB file, it would go though your VPS, get uploaded to backblaze. When a user looks at the uploaded image url, on the first request it gets requested from blackblaze, via your vps, and then gets cached on Cloudflare.
Then any extra requests from then on will be via Cloudflare. So you will technically be charged for some api requests and 1x 10MB of egress traffic.
I would recommend Backblaze B2 storage instead of removing post history.
The problem with post removal is that it will affect all other instances’ as you don’t (by default) cache original images from other fediverse instances (iirc)
So for example, my instance Reddthat will reference an image hosted on your instance, which will then 404. (But the thumbnail will be cached (I think))
Backblaze is dirt cheap and the pictrs object migration is now multi threaded making it very easy to migrate now. I was hosting 15GB and it amounted to bills of cents! $5/TB or $0.005 per GB. If you add CloudFlare Infront you then get free egress! Or any CDN that is part of the “Bandwidth alliance”. I now have ~120GB of pictrs storage. After 2-3 months.
Also, there was a recent chat on the lemmy admin matrix channel about setting some variable in pictrs so it does not cache any images. But I don’t remember what it was so maybe check the pictrs documentation.
What a hero!
Right? My Linux instance has been the same for 8 years. Same workflows, same no-nonsense. Every time I open the start bar on my work computer and it lags for 5 second to load some bull shit I don’t need I get so mad /rant
Sorry, but I just had to get that off my chest. What’s your setup like?
A faster db. Just the regular performance benefits, https://www.postgresql.org/about/news/postgresql-16-released-2715/
Also, Lemmy is built against v16 (now) so at some point it will eventually no longer JustWork
