Fix off_t overflow in pg_basebackup on Windows.
walmethods.c used off_t to navigate around a pg_wal.tar file that couldexceed 2GB, which doesn't work on Windows and would fail with misleadingerrors. Use pgoff_t instead.Back-patch to all supported branches.Author: Davinder Singh <davinder.singh@enterprisedb.com>Reported-by: Jakub Wartak <jakub.wartak@enterprisedb.com>Discussion:https://postgr.es/m/CAKZiRmyM4YnokK6Oenw5JKwAQ3rhP0YTz2T-tiw5dAQjGRXE3Q%40mail.gmail.com
