It's still a bunch of transaction logs, whereas differential and incremental
backups only backup the changed pages, no matter how many times they've been
changed.
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.
