+-- Simple optimization for report_files table - 80/20 solution
+
+-- ============================================
+-- 1. Add better index for the exact query pattern used
+-- ============================================
+-- The modify-reports-delta.ts does: WHERE id = ? AND deleted_at IS NULL
+-- This composite index will make that exact query much faster
+CREATE INDEX IF NOT EXISTS report_files_id_active_idx 
+ON report_files(id) 
+WHERE deleted_at IS NULL;
+
+-- ============================================
+-- 2. Add index for version_history JSONB queries
+-- ============================================
+-- Since we frequently access version_history to get version numbers
+CREATE INDEX IF NOT EXISTS report_files_version_history_gin_idx 
+ON report_files USING GIN (version_history);
+
+-- ============================================
+-- 3. Optimize the UPDATE pattern
+-- ============================================
+-- Create composite index for the UPDATE WHERE clause
+CREATE INDEX IF NOT EXISTS report_files_id_deleted_at_idx 
+ON report_files(id, deleted_at);
+
+-- ============================================
+-- 4. Add index for recent updates tracking
+-- ============================================
+-- Helps with finding recently modified reports
+CREATE INDEX IF NOT EXISTS report_files_updated_at_idx 
+ON report_files(updated_at DESC);
+
+-- ============================================
+-- 5. Optimize organization-based queries
+-- ============================================
+-- Many queries filter by org_id AND deleted_at
+CREATE INDEX IF NOT EXISTS report_files_org_id_deleted_at_idx 
+ON report_files(organization_id, deleted_at);
+
+-- ============================================
+-- 6. Update table statistics for query planner
+-- ============================================
