Logical replication does exist in pgsql, which is great. What it still lacks however (and I am sure they will very quickly catch up on) is the user facing process of being able to fix or sync a broken node without a rebuild. I'm also pretty sure pgsql logical replication is single threaded? Things like pg_rewind are layered on fixes that other database users don't have to depend on or learn. Except Oracle (because it's a mess).
