## Bug Report ### Which version of ShardingSphere did you use? [ecfad7e](https://github.com/apache/shardingsphere/commit/ecfad7e6fe572ad6a903b0ba92a8e93c56e3e3ae) ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy? ShardingSphere-Proxy ### Expected behavior No exception occurs when I connect Proxy with DataGrip ### Actual behavior ``` [ERROR] 2023-06-26 15:34:40.406 [Connection-1-ThreadExecutor] o.a.s.p.f.c.CommandExecutorTask - Exception occur: org.opengauss.util.PSQLException: [127.0.0.1:33518/ocalhost/127.0.0.1:5432] ERROR: relation "pg_stat_ssl" does not exist on gaussdb 位置：17 at org.opengauss.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:2901) at org.opengauss.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:2630) at org.opengauss.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:362) at org.opengauss.jdbc.PgStatement.runQueryExecutor(PgStatement.java:562) at org.opengauss.jdbc.PgStatement.executeInternal(PgStatement.java:539) at org.opengauss.jdbc.PgStatement.execute(PgStatement.java:397) at org.opengauss.jdbc.PgPreparedStatement.executeWithFlags(PgPreparedStatement.java:156) at org.opengauss.jdbc.PgPreparedStatement.executeQuery(PgPreparedStatement.java:112) at com.zaxxer.hikari.pool.ProxyPreparedStatement.executeQuery(ProxyPreparedStatement.java:52) at com.zaxxer.hikari.pool.HikariProxyPreparedStatement.executeQuery(HikariProxyPreparedStatement.java) at org.apache.shardingsphere.proxy.backend.handler.admin.executor.AbstractDatabaseMetaDataExecutor$DefaultDatabaseMetaDataExecutor.processMetaData(AbstractDatabaseMetaDataExecutor.java:174) at org.apache.shardingsphere.proxy.backend.handler.admin.executor.AbstractDatabaseMetaDataExecutor.execute(AbstractDatabaseMetaDataExecutor.java:76) at org.apache.shardingsphere.proxy.backend.handler.admin.DatabaseAdminQueryBackendHandler.execute(DatabaseAdminQueryBackendHandler.java:56) at org.apache.shardingsphere.proxy.frontend.postgresql.command.query.extended.Portal.bind(Portal.java:107) at org.apache.shardingsphere.proxy.frontend.postgresql.command.query.extended.bind.PostgreSQLComBindExecutor.execute(PostgreSQLComBindExecutor.java:55) at org.apache.shardingsphere.proxy.frontend.postgresql.command.query.extended.PostgreSQLAggregatedCommandExecutor.execute(PostgreSQLAggregatedCommandExecutor.java:41) at org.apache.shardingsphere.proxy.frontend.command.CommandExecutorTask.doExecuteCommand(CommandExecutorTask.java:126) at org.apache.shardingsphere.proxy.frontend.command.CommandExecutorTask.executeCommand(CommandExecutorTask.java:121) at org.apache.shardingsphere.proxy.frontend.command.CommandExecutorTask.run(CommandExecutorTask.java:78) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1136) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635) at java.base/java.lang.Thread.run(Thread.java:833) [INFO ] 2023-06-26 15:35:12.291 [HikariPool-2 connection adder] o.o.core.v3.ConnectionFactoryImpl - [a427b317-adf2-44f8-a314-1c41998033ec] Try to connect.
