They aim a completely different problems. The thing Joshua mentioned about BDR being *async* means that data will be *eventually* consistent. This tackles the problem with nodes which are distant (one node in London, another in NY, one in Tokio, ...) PgPools replication_mode is for nodes on a local network. It would never scale like BDR with geographically distant nodes. Conclusion, they don't solve the same problem, so it's hard to compare.
