Обсуждение: [DOCS] does pg_upgrade on Windows use junction points or hard links?
The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/9.6/static/pgupgrade.html Description: https://www.postgresql.org/docs/9.6/static/pgupgrade.html states that junction points are created when --link is used. https://msdn.microsoft.com/en-us/library/windows/desktop/aa365006(v=vs.85).aspx says that junction points are "soft links" (symbolic links in Unix speak), which would be disastrous if the original data directory is being purged afterwards. Is the documentation incorrect? Is the program correct?

It actually uses hard links on Windows as well. The documentation has been fixed and will appear correctly in the next minor releases. -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
