fn fetch_next(&mut self) -> Result<(usize, bool), PostgresSourceError>

Fetch next batch of rows from database, return (number of rows fetched to local, whether all rows are fechted from database). There might be rows that are not consumed yet when calling the next fetch_next. The function might be called even after the last batch is fetched.
