If the synchronization is triggered from the workstation with PostgreSQL on it, you can either use oracle_fdw or pg_dump/sql*loader to transfer the data. Using oracle_fdw is probably simpler, but it is not very performant for bulk update operations. If performance is the main objective, use export/import.
