I know it's coming from copy-and-paste, but
I believe the flags could be:
- dstfd = OpenTransientFile(tofile, O_RDWR | O_CREAT | O_EXCL | PG_BINARY);
+ dstfd = OpenTransientFile(tofile, O_CREAT | O_WRONLY | O_TRUNC | O_EXCL |
PG_BINARY);

The flags:
O_WRONLY | O_TRUNC

Allow the OS to make some optimizations, if you deem it possible.

The flag O_RDWR indicates that the file can be read, which is not true in
this case.
The destination file will just be written.

best regards,
Ranier Vilela
