Trying to mount my backup to a new Postgres database, but I got the error below:
2026-03-02 17:39:33.014 UTC [7] DETAIL: The data directory was initialized by PostgreSQL version 16, which is not compatible with this version 17.7 (Debian 17.7-3.pgdg13+1).

Hey, have you tried to change the source of the Postgres service where you are mounting the backup to ghcr.io/railwayapp-templates/postgres-ssl:16?
