  Description     : Advanced PostgreSQL & Pgbouncer Metrics Exporter for Prometheus

 PG Exporter is an advanced PostgreSQL & pgBouncer metrics exporter for
 Prometheus. It offers declarative config, dynamic planning, and customizable
 collectors. PG Exporter provides 600+ metrics and ~3K time series per
 instance, covers everything that is needed for PostgreSQL observability.
 .
 Its main features include:
 .
  * Highly Customizable: Define almost all metrics through declarative YAML
    configs
  * Full Coverage: Monitor PostgreSQL (10-19+) and pgBouncer (1.8-1.25+) in a
    single exporter
  * Fine-grained Control: Configure timeout, caching, skip conditions, and
    fatality per collector
  * Dynamic Planning: Define multiple query branches based on different
    conditions
  * Self-monitoring: Rich metrics about pg_exporter itself for complete
    observability
  * Auto-discovery: Automatically discover and monitor multiple databases
    within an instance
  * REST API: Comprehensive HTTP endpoints for service health, traffic routing
    and configuration reload
  * Extension Support: timescaledb, citus, pg_stat_statements,
    pg_wait_sampling,...
  * Local-first URL behavior: Built for on-host deployment, with implicit local
    target fallback and automatic `sslmode=disable` when omitted
