REVOKE (Resource Pool)
Revokes resource pool access privileges from users and roles.
Vertica checks resource pool privileges at runtime. Revoking a user's privileges for a resource pool can have an immediate effect on the user's current session. For example, a user query might require USAGE privileges on a resource pool. If you revoke those privileges from that user, subsequent attempts by the user to execute that query fail and return with an error message.
Syntax
REVOKE [ GRANT OPTION FOR ] { USAGE | ALL PRIVILEGES } ON RESOURCE POOL resource-pool[,…] FROM grantee[,…] [ CASCADE ]
