|
|
-- How it works:
|
|
-- 1. All grants previously created from the RBAC specification of this table will be deleted.
|
|
-- These grants are identified by `hs_office.relation.grantedByTriggerOf IS NOT NULL`.
|
|
-- User-induced grants (`hs_office.relation.grantedByTriggerOf IS NULL`) are NOT deleted.
|
|
-- 2. New role types will be created, but existing role types which are not specified anymore,
|
|
-- will NOT be deleted!
|
|
-- 3. All newly specified grants will be created.
|
|
--
|
|
-- IMPORTANT:
|
|
-- Make sure not to skip any previously defined role-types or you might break indirect grants!
|
|
-- E.g. If, in an updated version of the RBAC system for a table, you remove the AGENT role type
|
|
-- and now directly grant the TENANT role to the ADMIN role, all external grants to the AGENT role
|
|
-- of this table would be in a dead end.
