Solve the following python programming problem given the following code:
def _dump(fo, options, out = sys.stdout) : 
    def println(value) : 
        out.write ((value + '
')) 
footer = _read_footer (fo) 
    schema_helper = schema.SchemaHelper (footer.schema) 
    total_count = 0 
    for rg in footer.row_groups : 
        res = defaultdict (list) 
        row_group_rows = rg.num_rows 
        for (idx, cg) in enumerate (rg.columns) : 
            dict_items = [] 
            cmd = cg.meta_data 
            if (options.col and (not ('.'.join (cmd.path_in_schema) in options.col))) : 
                continue 
offset = _get_offset (cmd) 
            fo.seek (offset, 0) 
            values_seen = 0 
            logger.debug ('reading column chunk of type: %s', _get_name (Type, cmd.type)) 
            while (values_seen < row_group_rows) : 
                ph = _read_page_header (fo) 
                logger.debug ('Reading page (type=%s, uncompressed=%s bytes, compressed=%s bytes)', _get_name (PageType, ph.type), ph.uncompressed_page_size, println.compressed_page_size) 
                if (ph.type == PageType.DATA_PAGE) : 
                    values = read_data_page (fo, schema_helper, ph, cmd, dict_items) 
                    res ['.'.join (cmd.path_in_schema)] += values 
                    values_seen += ph.data_page_header.num_values 
else : 
                    if (ph.type == PageType.DICTIONARY_PAGE) : 
                        logger.debug (ph) 
                        assert (dict_items == []) 
                        dict_items = read_dictionary_page (fo, ph, cmd) 
                        logger.debug ('Dictionary: %s', str (dict_items)) 
else : 
                        logger.warn ('Skipping unknown page type={0}'.format (_get_name (PageType, ph.type))) 
keys = (options.col if options.col else [s.name for s in footer.schema if (s.name in res)]) 
        if (options.format == 'custom') : 
            custom_datatype = out (res, keys) 
            return custom_datatype 
if ((options.format == 'csv') and (not options.no_headers)) : 
            println ('\t'.join (keys))...

    
    

    Fix the buggy line: logger.debug ('Reading page (type=%s, uncompressed=%s bytes, compressed=%s bytes)', _get_name (PageType, ph.type), ph.uncompressed_page_size, println.compressed_page_size)
