QUICK QUERIES

Check Migration Status

-- Count tables from each migration
SELECT 'Migration 009' as migration, COUNT(*) as tables
FROM information_schema.tables
WHERE table_name IN ('users', 'api_keys', 'user_sessions', 'security_audit_log')
UNION ALL
SELECT 'Migration 017', COUNT(*)
FROM information_schema.tables
WHERE table_name IN ('mfa_config', 'mfa_backup_codes', 'mfa_verification_log', 'mfa_enrollment_sessions')
UNION ALL
SELECT 'Migration 018', COUNT(*)
FROM information_schema.tables
WHERE table_name IN ('roles', 'permissions', 'role_permissions', 'user_roles');

View RBAC Configuration

-- Role permission counts
SELECT * FROM role_permission_counts ORDER BY role_name;

-- User permissions (if user_roles populated)
SELECT * FROM user_permissions_view WHERE username = 'admin';

View NOTIFY Triggers

-- NOTIFY functions
SELECT proname FROM pg_proc WHERE proname LIKE 'notify_%';

-- NOTIFY triggers by table
SELECT c.relname, COUNT(*) as notify_triggers
FROM pg_trigger t
JOIN pg_class c ON t.tgrelid = c.oid
JOIN pg_proc p ON t.tgfoid = p.oid
WHERE p.proname LIKE 'notify_%'
GROUP BY c.relname
ORDER BY c.relname;

MANUAL NOTIFY TEST

Terminal 1 (Listener)

PGPASSWORD=foxhunt_dev_password \
psql -h localhost -p 5432 -U foxhunt -d foxhunt \
-c "LISTEN config_changed_trading;"

Terminal 2 (Trigger)

PGPASSWORD=foxhunt_dev_password \
psql -h localhost -p 5432 -U foxhunt -d foxhunt \
-c "UPDATE config_settings SET config_value = '\"999999\"'::jsonb WHERE config_key LIKE '%risk%' LIMIT 1;"

Expected Payload (Terminal 1)

{
  "operation": "UPDATE",
  "table": "config_settings",
  "key": "risk.max_daily_loss",
  "value": "999999",
  "old_value": "100000",
  "category": "risk",
  "timestamp": 1730000000.123,
  "id": "550e8400-e29b-41d4-a716-446655440000"

TROUBLESHOOTING

No NOTIFY Received

-- Check trigger exists
SELECT tgname FROM pg_trigger WHERE tgname LIKE '%notify%';

-- Check function exists
SELECT proname FROM pg_proc WHERE proname = 'notify_config_change';

-- Test manually
SELECT pg_notify('config_changed_global', '{"test": "payload"}');

Permission Query Slow

-- Check indexes
SELECT indexname FROM pg_indexes WHERE tablename = 'user_roles';

-- Analyze table statistics
ANALYZE users;
ANALYZE user_roles;
ANALYZE role_permissions;

Empty Results

-- Check if roles assigned
SELECT COUNT(*) FROM user_roles;

-- Check if permissions mapped
SELECT COUNT(*) FROM role_permissions;

-- List all users
SELECT username, role, is_active FROM users;

SERVICE INTEGRATION

Rust Service Example

use tokio_postgres::Client;

// Listen to channel
client.execute("LISTEN config_changed_trading", &[]).await?;

// Process notifications
let mut stream = client.notifications();
while let Some(notification) = stream.next().await {
    let channel = notification.channel();
    let payload: ConfigPayload = serde_json::from_str(notification.payload())?;

    match channel {
        "config_changed_trading" => reload_trading_config(payload).await?,
        "permissions_changed" => invalidate_permission_cache().await?,
        _ => {}
    }
}

SECURITY FEATURES

• Row Level Security (RLS) on sensitive tables
• SHA-256 API key hashing
• AES-256 TOTP secret encryption
• Password hashing with pgcrypto
• Audit logging for security events
• Session expiration
• Rate limiting (60/min, 1000/hour)
• MFA lockout (5 failed attempts, 15 min)
• Cascade delete for user data

---

NEXT STEPS

1. ✅ Populate config_settings with production values
2. ✅ Assign user roles for system accounts
3. ✅ Test NOTIFY/LISTEN with services
4. ✅ Implement service-side LISTEN handlers
5. ✅ Add config validation in services
6. ✅ Set up monitoring for NOTIFY events
