Current database is not set

升级到4.0.6版本后
url: jdbc:mysql:loadbalance://doriscluster-sample-fe-2.doriscluster-sample-fe-internal.doris.svc.cluster.local:9030,doriscluster-sample-fe-0.doriscluster-sample-fe-internal.doris.svc.cluster.local:9030,doriscluster-sample-fe-1.doriscluster-sample-fe-internal.doris.svc.cluster.local:9030/chief_quote_deriv?loadBalanceConnectionGroup=readGroup&loadBalanceStrategy=roundRobin
如果不用loadbalance，单节点连接是没有问题的
错误：Current database is not set
3.0.8版本正常
