If you find a platform with 64 bit file offsets that doesn't support 64 bit integral types I will not just be surprised but amazed. > One alternative, which I am not terribly fond of, is to have pg_dump > write multiple files - when we get to 1 or 2GB, we just open another > file, and record our file positions as a (file number, file > position) pair. Low tech, but at least we know it would work. That does avoid the issue completely, of course, and also avoids problems where a platform might have large file support but a particular filesystem might or might not. > Unless anyone knows of a documented way to get 64 bit uint/int file > offsets, I don't see we have mush choice. If you're on a platform that supports large files it will either have a straightforward 64 bit off_t or else will support the "large files API" that is common on Unix-like operating systems. What are you trying to do, exactly? Regards, Giles ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
