It's actually not "Windows" providing hard links, it is the file system
NTFS. FAT and its modern cousins don't provide hard links - but this will
rarely be used for databases these days.=20
However, ReFS (introduced with server 2012 and providing some new features
like automatic integrity checks, clustering etc.) does no longer provide
hard links.=20
Are hard links used anywhere else but in pg_upgrade?
