What problem does it solve? PostgreSQL work inside the HX Eco-System risks being derailed by generic tutorials, managed-service assumptions, or third-party advice that conflicts with HX's native-Linux, systemd-based architecture and strict validation gates. This Skill reconciles current PostgreSQL Global Development Group documentation and reviewed external expertise against HX authority so recommendations never override server placement, deployment standards, or smoke-test criteria. ## Core Features & Use Cases - Authority reconciliation: Classifies every material recommendation as ACCEPT, ADAPT, REJECT_FOR_HX, or OWNER_DECISION_REQUIRED against a defined precedence chain from owner decisions down to general model knowledge. - HX-9 deployment discipline: Enforces native systemd deployment, shared-host boundaries with Redis, version/package-source pinning, and network/authentication rules before any configuration change. - Governed validation: Anchors acceptance to the exact PostgreSQL smoke-test contract (TEMP table known-answer proof, MCP companion gate, reboot persistence) rather than vendor quickstarts. - Use Case: When planning the HX-9 PostgreSQL build, use this Skill to verify the current supported PostgreSQL major against PGDG guidance, flag unpinned decisions like package source or listener configuration as OWNER_DECISION_REQUIRED, and reject container-based deployment suggestions. ## Quick Start Ask the agent to plan the HX-9 PostgreSQL installation using the HX PostgreSQL Advisor and identify which decisions require owner approval before execution.
