Hi, I’m having problems rebuilding my multisite discourse install. I get the errors pasted below. I’m running ./launcher rebuild app as root. git status in /var/discourse says I’m up to date with branch main. it reports running postgres 15.13: 2025-08-14 10:35:04.390 UTC [45] LOG: starting Post…

I solved it in postgres (first I had to restart docker with `service restart docker`) ./launcher enter app sudo -u postgres psql then running this for each site’s database: \c b_discourse CREATE EXTENSION IF NOT EXISTS vector;

Build error: permission denied to create extension "vector"

Are you doing this as a root user (ran sudo -s before this)?
