Hello, hackers!
initdb on my windows 10 system stopped working after the commit
c5cb8f3b: "Provide lstat() for Windows."
The error message is: creating directory C:/HOME/data ... initdb:
error: could not create directory "C:/HOME": File exists
"C:/HOME" is the junction point to the second volume on my hard drive -
"\??\Volume{GUID}\" which name pgreadlink() erroneously strips here:
https://github.com/postgres/postgres/blob/7e29a79a46d30dc236d097825ab849158929d977/src/port/dirmod.c#L357.
So initdb could not stat the file with name "Volume{GUID}", tried to
create it and failed.
With the attached patch initdb works fine again.
