In the current version of Cloudberry, it is not possible to modify the owner of a STORAGE SERVER object or add a descriptive comment to it after it has been created. The corresponding DDL commands, ALTER STORAGE SERVER ... OWNER TO ... and COMMENT ON STORAGE SERVER ..., are not supported and result in a syntax error.
This limitation creates a gap in the database's object management capabilities. For most other database objects (like tables, functions, etc.), it is standard practice to allow modification of ownership and comments, which is crucial for database administration, security, and documentation.
