-- HOWTO: Rebuild RBAC-system for table hs_office.bankaccount after changing its RBAC specification.
--
-- begin transaction;
--  call base.defineContext('re-creating RBAC for table hs_office.bankaccount', null, <<insert executing global admin user here>>);
--  call hs_office.bankaccount_rebuild_rbac_system();
-- commit;
--
-- 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.bankaccount.grantedByTriggerOf IS NOT NULL`.
--    User-induced grants (`hs_office.bankaccount.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.
