This commit improves the performance of page-level, or differential backup, by not having to scan anymore all the pages of a relation file, something that can be very long on large data sets, but by scanning the list of blocks changed by WAL records since the last full or differential backup. As a restriction and to avoid potential data corruption should hint-bit updates occur on a page, backups can only be taken from a server that has wal_log_hints or data checksums enabled. Base patch by Yury Zhuravlev, heavily modified by me. |
