Thx! I had no idea this existed, and I love it. |
|
Looks good, please change the one in |

I'll make the requested changes soon. |

As a data point, we've added Debian based pgautoupgrade images now too ( If your existing PostgreSQL docker image is Debian based, then it's best to use a Debian based pgautoupgrade image. That's because we've had reports of collation problems when people upgraded their Debian based PostgreSQL image using our original (Alpine based) images. These new images should fix that. 😄 |
|
Heh, and now I've looked at the actual PR (a simple 1-liner), and it's alpine based anyway. You should be good to go. 😄 |
|
I've fixed the other cases now. |
Thanks. Sorry I didn't get to it - I've been busy with other things. |
|
No probs. |

There was a problem hiding this comment.
As @ticoombs mentioned, these migration scripts arent needed anymore. However they are still linked in Lemmy release announcements, so I would leave them in but remove everything except for this line:
sudo sed -i "s/image: .*postgres:.*/image: pgautoupgrade\/pgautoupgrade:16-alpine/" ./docker-compose.yml

Lemmy changed from PostgreSQL 15 to 16 at some point, and trying to switch from 15 to 16 in
docker-compose.ymlresults in errors like this at startup:This PR changes the PostgreSQL container to use pgautoupgrade. The pgautoupgrade image is based on the regular PostgreSQL one, but it automatically updates the data to the newer format on startup. This avoids users having to figure it out manually.
