DiscoverAdvertisedAddr promised to return an error rather than a fallback no peer can dial, but only rejected an unspecified address. With PostgreSQL on the same host or pod as a replica, which is compose, single-node and any sidecar layout, the route to it is loopback, so every replica advertised 127.0.0.1 and a peer dialling that reached itself. Loopback, link-local and zoned source addresses are now rejected with an error naming the remedy, and a port outside 1-65535 is rejected before it becomes an undialable address. Liveness was also measured on each replica's own clock: Register and Heartbeat stamped last_seen from the Go process, and Live compared those rows against the reading replica's time.Now(). Skew therefore shrank or stretched the window by writerBehind+readerAhead, evicting healthy peers or keeping dead ones. Both sides now use the database clock, which is the one clock every replica demonstrably shares. Assisted-by: Claude Opus 5 [claude-code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io>
