Hi Victor, I rebased and simplified this, and added a lot of tests to be able to understand what it does. I think all systems that didn't have this are now EOL and we don't need to support them in PG16, but perhaps our _WIN32_WINNT is not quite high enough (this requires Win10 RS1, which itself was EOL'd in 2019); the main question I have now is what happens when you run this on non-NTFS filesystems, and whether we want to *require* this to work because the non-POSIX support will probably finish up untested. I posted all that over on a new thread where I am tidying up lots of related stuff, and I didn't want to repost the proposed testing framework in multiple threads... https://www.postgresql.org/message-id/flat/CA%2BhUKG%2BajSQ_8eu2AogTncOnZ5me2D-Cn66iN_-wZnRjLN%2Bicg%40mail.gmail.com
