cherrylzhao opened a new issue #5386:
URL: https://github.com/apache/shardingsphere/issues/5386
## Bug Report
### Which version of ShardingSphere did you use?
\> 4.0.0
### Which project did you use? Sharding-JDBC or Sharding-Proxy?
sharding-proxy
### Expected behavior
succeed getIndexInfo through metadata, code is as below
``` java
@Test
public void assertProxy() throws SQLException {
Connection connection =
DriverManager.getConnection("jdbc:postgresql://localhost:3307/sharding_db?user=root&password=root");
ResultSet resultSet = connection.getMetaData().getIndexInfo(null,
null, "t_order", false, true);
while (resultSet.next()) {
ResultSetMetaData resultSetMetaData = resultSet.getMetaData();
for (int i = 1; i <= resultSetMetaData.getColumnCount(); i++) {
System.out.println(String.format("%s: %s",
resultSetMetaData.getColumnLabel(i), resultSet.getObject(i)));
}
}
}
```
### Actual behavior
```
org.postgresql.util.PSQLException: ERROR: column am.amcanorder does not exist

```
### Reason analyze (If you can)
it seems sharding-proxy could not compatible with postgresql greater than
9.4, maybe we should enhance handshake packet
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule
configuration, when exception occur etc.
1. start the proxy, test it using above code
