Thank you for reply.

I do not think the root cause of this problem is about privilege,and this windows machine is my test machine, only I have access to this machine.

I think this problem is a bug,there are two evidences:

The first evidence :

This probably means the PostgreSQL user/process does not have access to
the file, either because it does not exist, lack of privileges, an AV
system blocking the access, or something like that.
 
I suggest you seach in the Windows Event Log, and various other logs you
might have there.

Ah, I haven't noticed the information about file size in the first post,
as it was buried at the very end :-(

In that case, I think Tom is right it's likely the same issue as [1],
although that starts with a report about issues with 4GB. Maybe that's
due to using different windows version 2008 R2 vs. 2012 R2, though.

It'd be good if you could test the latest patch [2] in that thread.
You'll need to build PostgreSQL on Windows, though - I don't have much
experience with that, but there are wiki pages about doing that either
using Visual Studio [3] or mingw [4].
