Fix WAL file replacement during cascading replication on Windows. When the startup process restores a WAL file from the archive, it deletes any old file with the same name and renames the new file in its place. On Windows, however, when a file is deleted, it still lingers as long as a process holds a file handle open on it. With cascading replication, a walsender process can hold the old file open, so the rename() in the startup process would fail. To fix that, rename the old file to a temporary name, to make the original file name available for reuse, before deleting the old file.
