desc: When performing an order by sorting query on the shard table, the following error is reported. When looking at the code, it is found that for PostgreSQL type databases, the default schema is public, and data is obtained in public based on the shard table name. However, schema.public

There's nothing in it, is there any special configuration to be made for the shard table
