+/**
+ * {@link BackendFactory} that builds a {@link PostgresQueueBackend}.
+ *
+ * The returned backend owns its {@link PostgresConnection} (a `pg.Pool` plus a
+ * dedicated `LISTEN` client); the high-level classes depend only on
+ * `IQueueBackend` and never touch a `pg` client directly.
+ *
+ * The `opts.connection` value is forwarded to {@link PostgresConnection} and may
+ * be a connection string, a node-postgres pool config (optionally carrying a
+ * `schema`), or an already-built `pg.Pool` instance. `pg` is lazily required
+ * only when a config/string is passed, so Redis-only users never need it
+ * installed.
+ *
+ * Inject this into the queue classes (or set it as the process-wide default via
+ * `setDefaultBackendFactory(createPostgresBackend)`) to back BullMQ with
+ * PostgreSQL.
