There is some documentation to do that with Visual Studio:
https://www.postgresql.org/docs/devel/install-windows.html
In my case, I just use a command prompt to launch those commands and
do the work.  I can send you links to download custom builds, of
course.  My guess is that these should be able to work on your host,
as Windows is good in terms of backward-compatibility.

Thanks.  The .deleted files come from RemoveXlogFile() where a file
gets removed.  This means that a rename before doing an unlink()
fails.  What we are looking for here is what is holding those files
back.
