Add separate CLUSTER grant In case you have different roles for the same user on multiple clusters, ON CLUSTER query can help to overcome some limitations. Consider the following example: - cluster_with_data, dev_user (readonly=2) - stage_cluster, dev_user (readonly=0) So when you will execute the following query from stage_cluster, it will be successfully executed, since ON CLUSTER queries has different system profile: DROP DATABASE default ON CLUSTER cluster_with_data This is not 100% safe, but at least something. Note, that right now only ON CLUSTER query it self is supported, but separate clusters are not (i.e. GRANT CLUSTER some_cluster_name TO default), since right now grants sticked to database+. v2: on_cluster_queries_require_cluster_grant v3: fix test and process flags as bit mask Signed-off-by: Azat Khuzhin <a.khuzhin@semrush.com> 2022-03-30 08:32:49 +00:00			`<on_cluster_queries_require_cluster_grant>true</on_cluster_queries_require_cluster_grant>`
