Is there a way to pass an `objective` parameter or an `eval_metric` to xgboost ? Or any other algo ? There seems to be a [definitive list of supported hyperparameters defined on PostgresML side](https://github.com/postgresml/postgresml/blob/master/pgml-extension/src/bindings/xgboost.rs#L71) but it doesn't seem to support any of them. I would like to `eval_metric = 'mae'` for price prediction and `objective = 'reg:logistic'` for duplicates detection as documented here: https://xgboost.readthedocs.io/en/stable/parameter.html The equivalent python code ```python model = XGBRegressor(objective="reg:linear", eval_metric="mae") ```
