### Reason analyze (If you can)
Shardingsphere seems response "68" to grafana.
The network packet capture results show that the packets replied by ss is no-data.Error
Possible problematic code:
```
org.apache.shardingsphere.proxy.frontend.postgresql.command.query.extended.describe.PostgreSQLComDescribeExecutor#describeInsertStatementByDatabaseMetaData
```
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
Abnormal SQL:
```sql

This could be reproduced by JDBC.
```sql
create table t (id serial primary key, val varchar not null);
```
```java
try (Connection connection = DriverManager.getConnection("jdbc:postgresql://127.0.0.1:55432/postgres?prepareThreshold=1", "postgres", "postgres")) {
try (PreparedStatement preparedStatement = connection.prepareStatement("insert into t (val) values (?) returning id")) {
ResultSetMetaData metaData = preparedStatement.getMetaData();
metaData.getColumnName(1);
}
}
```
```
Exception in thread "main" java.lang.NullPointerException: Cannot invoke "java.sql.ResultSetMetaData.getColumnLabel(int)" because "metaData" is null
