## Properties


| Property | Modifiers | Type | Description |
| --- | --- | --- | --- |
| [appName](https://imqueue.org/api/pg-pubsub/latest/pg-pubsub.pgclient.appname/) |  | string | 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. |
