In the yml file the image points to bitnami/supabase-postgres:$$cap_app_version. The official image is at supabase/postgres now.
The volume/persistent info will likely need to be updated as well. I used /var/lib/postgresql/data as the path in the container and pgdata for the label. It seems the default username needs to be supabase_admin.
With these changes I was able to get supabase postgres working.
