1. In loadServices() function, where you set DB connection in DI add:

    //Example register a 'db' service in the container
    $di->set('db', function () use ($config) {
        $connection = new \Phalcon\Db\Adapter\Pdo\Mysql([
            'host' => $config->database->host,
            'username' => $config->database->username,

        if ($config->sql_debug) {
            $eventsManager = new \Phalcon\Events\Manager();

            \CarlosEkt\PSQL_Debug::getInstance()->init(SYSTEM_START_TIME);
            $eventsManager->attach('db', function ($event) {
                /** @var Phalcon\Events\Event $event */
                if ($event->getType() === 'beforeQuery') {
                    \CarlosEkt\PSQL_Debug::getInstance()->queryStart(microtime(true));
                }
                if ($event->getType() === 'afterQuery') {
                    $sql = \CarlosEkt\PSQL_Debug::getInstance()->getLastQuery(true);
                    \CarlosEkt\PSQL_Debug::getInstance()->queryEnd($sql, microtime(true));
                }
            });
