Hi Hackers, I've updated the wiki page https://wiki.postgresql.org/wiki/Incremental_backup following the result of discussion on hackers.
Compared to first version, we switched from a timestamp+checksum based approach to one based on LSN. This patch adds an option to pg_basebackup and to replication protocol BASE_BACKUP command to generate a backup_profile file. It is almost useless by itself, but it is the foundation on which we will build the file based incremental backup (and hopefully a block based incremental backup after it). Any comment will be appreciated. In particular I'd appreciate comments on correctness of relnode files detection and LSN extraction code.
