The following bug has been logged on the website:

Bug reference: 17288
Logged by: Dmitry Koval

PostgreSQL version: 14.1
Operating system: Windows 10 (21H1)
Description:

Hi,
there is a problem on the REL_14_STABLE branch (on the REL_14_1
branch too). When executing a query under Windows 10 (21H1)

\copy (SELECT 1) TO stdout

PSQL utility prints error
"could not stat file" (null) ": Invalid argument" and crashes.
There is no error under Ubuntu 20.04 LTS.

Issue source: commit bed90759fcbcd72d4d06969eebab81e47326f9a
("Fix our Windows stat() emulation to handle file sizes > 4GB.",
discussion: https://postgr.es/m/15858-9572469fd3b73263@postgresql.org)

In this commit function stat () was replaced to function
GetFileInformationByHandle()
(see src/port/win32stat.c, function fileinfo_to_stat()):

if (!GetFileInformationByHandle(hFile, &fiData))
{
_dosmaperr(GetLastError());
return -1;
}

Function GetFileInformationByHandle() works for files but can not work
with streams like "stdout".
For "stdout" the GetFileInformationByHandle () function returns an error
(GetLastError () == ERROR_INVALID_FUNCTION), which causes PSQL crash.

Examples of errors processing for function GetFileInformationByHandle()
in other applications:

1) https://github.com/python/cpython/blob/main/Modules/posixmodule.c
2)
https://doxygen.reactos.org/da/d6a/subsystems_2mvdm_2ntvdm_2hardware_2disk_8c_source.html

Quick fix in src/port/win32stat.c:
in case function GetFileInformationByHandle() returns a specific error
code, call the _stat64() function for this descriptor.
It's not elegant, but it works.

(I'll attach file with patch in next email).

With best regards,
Dmitry Koval.
