I want to store the validation results back into the postgres database.

I tried changing the store backend, but that doesn’t seem to work with v1. Any help would be appreciated!
validation_results_store:
class_name: ValidationResultsStore
store_backend:
class_name: TupleFilesystemStoreBackend
base_directory: uncommitted/validations/

validation_results_store:
class_name: ValidationResultsStore
store_backend:
class_name: TuplePostgresStoreBackend
connection_string: ${POSTGRES_CONNECTION_STRING}
