Signal to Action: pgwd's Three-Tier Model for PostgreSQL Reliability

pgwd transforms PostgreSQL connection monitoring from reactive threshold alerts into a framework for proactive operational decision-making. By providing tiered alerts (75/85/95%) with actionable context—including active/idle connection breakdown—teams can identify pressure patterns before hitting fatal limits and respond with infrastructure-aware mitigations. This approach demonstrates how production reliability evolves beyond simple alerting to signal-to-action systems that respect both system constraints and resource realities.
