How long, in milliseconds, [PgPubSub.destroy()](https://imqueue.org/api/pg-pubsub/latest/pg-pubsub.pgpubsub.destroy/) waits for a graceful shutdown before giving up. Read from `PG_PUBSUB_SHUTDOWN_TIMEOUT`, default 1000.

The wait matters because releasing a lock cleanly is what lets a standby take over immediately: the release deletes the lock row, which fires a NOTIFY the waiting processes are listening for. A shutdown that is killed before the release completes falls back to [ACQUIRE\_INTERVAL](https://imqueue.org/api/pg-pubsub/latest/pg-pubsub.acquire_interval/) instead.
