The prior source review was on 2026-09-26: the original publication date is retained; the text below reflects the implementation reviewed on this date. See <a href="https://barn.pgsty.com/docs/about/status/">Status</a> for released versus candidate behavior and dated acceptance evidence.</p> </div> </div><p>A Pigsty Inventory names machines by stable addresses. PostgreSQL replication, etcd membership, HAProxy backends, VIPs, monitoring targets, and Ansible all assume that <code>10.10.10.11</code> continues to mean the same node. A loopback port forward can expose SSH or PostgreSQL to the host, but it cannot provide that network identity to peers.</p>
