Reply from Microsoft is as below.

"This is regarding a long pending case where stat() was failing on
hard links and causing an infinite loop. We have discussed this
multiple times internally and unfortunately do not have a commercially
viable solution to this issue. Currently there are no workarounds
available for this issue, but this has been marked for triage in future
OSes. Since we have out run the maximum time that can be spent
on this Professional Level Service request, I have been asked to
move ahead and mark this as a won’t fix. We would need to close
this case out as a won’t fix, and you would not be charged for this

nor a fix for this issue in Windows.  I think now we need to decide on
which solution we want to pursue for PostgreSQL.  Does any one of
the above approaches seems sensible or let me know if you have any
other idea to solve this problem.
