feels like it 2025-02-02 22:44:44.579 UTC [35] DETAIL: The data directory was initialized by PostgreSQL version 13, which is not compatible with this version 15.10 (Debian 15.10-1.pgdg120+1).
that I had PostgreSQL version 13, but the rebuild script is turning off version 15, so the postgres was actually not shut down?
update:
verified: it’s PostgreSQL version upgrade related
running ./launcher rebuild app succeeded, when I changed "templates/postgres.template.yml" to "templates/postgres.13.template.yml" to postponing the postgres update
