## Question **For English only**, other languages will not accept. Before asking a question, make sure you have: - Googled your question. - Searched open and closed [GitHub issues](https://github.com/apache/shardingsphere/issues). - Read documentation: [ShardingSphere Doc](https://shardingsphere.apache.org/document/current/en/overview). Please pay attention on issues you submitted, because we maybe need more details. If no response anymore and we cannot reproduce it on current information, we will **close it**. Hello, I encountered the following error while trying to migrate data using sharding-proxy. The test database is postgeSQL. ``` sharding_db=> insert into person select * from person2; **ERROR: java.lang.NullPointerException** sharding_db=> \copy person from '/home/agens/person_0_0.csv' delimiter '|' csv header ; **ERROR: COPY from stdin failed: COPY commands are only supported using the CopyManager API.** CONTEXT: COPY person, line 1 ``` Doesn't it support postgresql's COPY FROM and INSERT INTO SELECT statements or pg_dump now? If so, are there any plans to support that feature? Then, when using shardingsphere for the first time in postgresql, if data needs to be migrated, how should it be migrated? -- This is an automated message from the Apache Git Service.
