That's a serious reduction in disk space, and time to apply them. I think everybody agrees that incremental backup per database, and not cluster-wide, is nice, and it would be nice if PG supported it. But, given the way PG is architectured, having cluster-wide WALs, that's not an easy task to implement. Repeating "other databases have it" doesn't change that. -- Andreas Joseph Krogh
