Hi hackers.

When I using a Non-Exclusive Low-Level Backup on windows, "invalid data in file backup_label" will be shown.

The code are listed below

    if (fscanf(lfp, "START WAL LOCATION: %X/%X (file %08X%16s)%c",
               &hi, &lo, &tli_from_walseg, startxlogfilename, &ch) != 5 || ch != '\n')
        ereport(FATAL,
                (errcode(ERRCODE_OBJECT_NOT_IN_PREREQUISITE_STATE),
                 errmsg("invalid data in file \"%s\"", BACKUP_LABEL_FILE)));

When I wrote the backup_label on windows, CRLF will at the end of line, so the ch will be '\r'.

I'm not sure that these two files(tablespace_map and backup_label) should not use CRLF new line style is mentioned in
manual[1].
How about setting the text mode when reading these 2 files like patch listed in attachment?

Any thought?
