Hi, dbt might not be the right tool for you if you want to “version control” an entire Snowflake database. dbt is specifically about building data models for analytics, so is primarily focused on creating tables and views. It doesn’t cover sequences, or many other Snowflake objects like stages, integrations, tasks, users etc.
That said, you can potentially create your own custom materialization that generates a sequence: https://docs.getdbt.com/docs/guides/creating-new-materializations/
