If there are no connections available in the pool then postgreSQLClient.rxGetConnection() waits until a connection is available, If we have some slow query then the wait queue is growing indefinitely as waiters queue does not have any maxLimit and because of this we have response times going high/spiking as waiters queue grows, Is it a good idea to add 'maxWaitersQueueSize' parameter and any new connection request will be failed immediately after this size reached and caller can return a default response(operating in degraded mode), Or was there a specific reason we did not add this sizeLimit on waiters queue ?
