enrich is only available for Databricks relations

Error message

enrich is only available for Databricks relations

What it means

relation_enrich (backing get_column_and_constraints_sql) downcasts the inner relation to the Databricks Relation implementation; on any other adapter's relation type the downcast fails and this guard fires — enrichment with constraints is a Databricks-only capability.

Solutions

1. Call enrich only for Databricks relations (gate in the macro)
2. Add an enrich path for other adapters if constraints support is needed there
3. Return a structured error instead of a bare minijinja InvalidOperation

When it happens

Trigger: Thrown at crates/dbt-adapter/src/relation/relation_object.rs:100 when the library encounters an invalid state.
