Replication from CloudSQL Postgres to BigQuery

Hi everyone, does anyone know if Datastream or Datafusion support Postgres as a replication source to Bigquery? If neither of these are options, would the next best options be using Federated queries or using a Postgres to BigQuery connector provided by companies like FiveTran? We also have cloud composer setup and could stick with our own replication using airflow operators or triggering dataflow jobs. Thanks!
