While indeed very exciting, it's important to note that this makes the BDR extension from 2ndquadrant compatible with stock Postgres. This does not include BDR shipping with core Postgres.

This continued improvement with the core code and extension APIs will make more and more extensions feasible which will mean more are able to plug-in and add value without things having to be committed to core. Though in time this is one that has a good chance of actually being in core much like pg_logical.

Bi-Directional Replication for PostgreSQL (Postgres-BDR, or BDR) is the first open source multi-master replication system for PostgreSQL to reach full production status, developed by 2ndQuadrant and assisted by a keen user community. BDR is specifically designed for use in geographically distributed clusters, using highly efficient asynchronous logical replication, supporting anything from 2 to more than 48 nodes in a distributed database.

Why specify a range if you're going to leave it open-ended?

It's good to know what range people have tested with, even if it's not a hard cap.
