Function database

database(): Promise<
    | {
        status: string;
        latency: number;
        timestamp: string;
        error?: undefined;
    }
    | { latency?: undefined; status: string; error: string; timestamp: string },

Checks database connectivity and measures query performance.

Executes a simple test query to verify database connectivity and measures response latency. Returns health status with connection details and performance metrics. Essential for monitoring database availability in production environments.

Returns Promise<
    | {
        status: string;
        latency: number;
        timestamp: string;
        error?: undefined;
    }
    | { latency?: undefined; status: string; error: string; timestamp: string },

Database health status with latency metrics
Example
```
const dbHealth = await healthChecks.database();
if (dbHealth.status === 'healthy') {
  console.log(`Database responding in ${dbHealth.latency}ms`);
} else {
  console.error(`Database error: ${dbHealth.error}`);
}
```
