Value PostgreSQL reports as `application_name` for this connection.

Load-bearing rather than cosmetic: the lock's liveness check looks the holder up in `pg_stat_activity` BY this name to decide whether it is still alive, so two processes sharing an appName cannot be told apart, and a blank one defeats the check.

**Signature:**

```typescript
appName: string;
```
