Regarding the [PARSE_SYNTAX_ERROR] Syntax error at or near 'OWNER'.Remember to wrap the new owner name in the SQL statement with the Grave Accent (`) as the below sample. ALTER SCHEMA schema_name OWNER TO `new_oner_name`;
Yes! Cluster's owner/creator can be changed with the REST API - POST /api/2.1/clusters/change-ownerRequest Body sample:{
"cluster_id": "string",
"owner_username": "string"
}Ref: Clusters API | Change cluster ownerHope this helps!
