an unclear problem related to the work of qsqlquery, namely with the query.value() command

Question

When running this program code, it is concluded that the database is connected, as well as that the dimension of query = 2, after which an error occurs when trying to call the guery.value function. The Segmentation Fault error, why it happens is unclear. I need help. Here is the program code:

QSqlDatabase db = QSqlDatabase::addDatabase("QPSQL", "cash");
db.setConnectOptions("requiressl=1;connect_timeout=2");
db.setHostName("rdbmsastra.vt");
db.setPort(5432);
db.setDatabaseName("cvcomputer");
db.setUserName("astra");
db.setPassword("123451");
db.open();
if (db.isOpen()){
    qDebug() << "Success open DB";
} else qDebug() << "FAIL" << db.lastError().text();

QSqlQuery query("select * from status", db);
qDebug() << query.size();
while(query.next()){
    qDebug() << query.value("id_s").toInt();
    qDebug() << query.value("discription").toString();
}

programming takes place on windows 10 in qt creator.

I hope for your help
