Repair backup failed (the value of segment_size is greater than 2G)

[hslightdb]

If the value of segment_size is greater than 2G, the file length will overflow. In this case, the backup will fail.

@funny-falcon ,I see this problem still exists, are there any plans to fix this?

Currently there are no plans to fix it, since it quite hard due to backward compatibility issues.

Ah, I see: your patch is quite capable. Ok, let me think once more.

@funny-falcon ,It seems n_blocks variable type is int ( file->n_blocks = (int) n_blocks) ,postgrespro has already fixed the (xid 32bit) issue, I think no reason why it can't be fixed!,Thank you very much
