PG_RMAN can do incremental backups. I think it does the same thing as
Oracle without enabled block change tracking: it backs up all the files
changed since the last full backup. However, that doesn't help you much
because of the vacuum which can touch the file well after it has been
referenced in transaction. I like pg_rman because it can automatically
delete old backups and keep only 4 latest backups.
