  • Bloom filter indexes on compressed columns can return incorrect query results before upgrade
  • PostgreSQL 15 support ending June 2026, forcing mandatory upgrades to PostgreSQL 16 or later

Wattwatchers EMS

  • Requires hardware installation at each monitoring point, increasing total cost of ownership
  • Built for small to medium portfolios; scaling to large portfolios may present usability challenges
  • Limited to energy monitoring; not a comprehensive building management system
