Upgrade failed. Database stopped. (multisite install)

Installation

I logged in. Haven’t updated in 11 months. Started with trying to upgrade the Docker Manager. It never seemed to complete. Next day the admin page was pretty much borked. I tried to do the ./launcher rebuild app. I get the

2025-10-30 20:04:52.144 UTC [1892] discourse@c_discourse STATEMENT:  ALTER EXTENSION vector UPDATE TO ‘0.7.0’;

But the database is stopped so the fixes I saw don’t work.

EDIT: It looks like the DB is still in 13 format?

If you haven’t seen the topic PostgreSQL 15 update - Announcements you might start there. It discusses a number of issues and recommendations.

Thanks. Too much to really grok it all but nothing seems like my problem. :frowning: The database seems to run during the rebuild process which is the strange part. At least from what I can tell in the stuff that scrolls by.

That’s mostly never going to work after 11 months.

Your definitely need to do the postgres 15 upgrade, and that’s part of what’s wrong. It’s possible that that can switch to the postgres 13 and get things going again before doing the upgrade.

Is this a standard install ?
