-- =============================================================================
-- CVE Dashboard — Complete PostgreSQL Schema (v1.0.0)
-- =============================================================================
-- Translates the full SQLite schema (setup.js) to PostgreSQL 16.
-- Designed for idempotent execution: safe to run multiple times via psql or
-- pool.query() without errors or duplicate data.
--
-- Usage:
--   psql -h localhost -p 5433 -U steam -d cve_dashboard -f backend/db-schema.sql
--   OR
--   const schema = fs.readFileSync('backend/db-schema.sql', 'utf8');
