I understand that using Postgres without WAL is quite fault-INtolerant (although considerably more performant). But what about the setups of YDB and CockroachDB, are they comparable to Postgres' setup in terms of fault tolerance?

Absolutely. Both CockroachDB and YDB have replication factor equal to 3. So it's similar to Postgres with 2 sync replicas.
