A
pool.query()that timed out waiting for a connection kept its place in the wait queue, so a later request failed at once withConnectionPoolTooBusyExceptionalthough nothing was waiting, and the queue metric stayed inflated. The timer now cancels the waiter before failing the request, likegetConnection()does. The test runs against PostgreSQL with a pool of one connection and a wait queue of one.
