-- Lossy revert: this removes the three independent Custom collection permissions, which the legacy -- role/access_all schema cannot represent -- it only knows all three together. The revert therefore -- requires the same acknowledgement as 2026-07-24-140000/down.sql -- which only announces the loss, -- it does not authorize it. Create the marker table while every Vaultwarden instance is stopped: -- -- CREATE TABLE __vw_allow_custom_role_downgrade (acknowledged INTEGER NOT NULL PRIMARY KEY); CREATE TEMPORARY TABLE __vw_custom_role_downgrade_guard ( blocked INTEGER NOT NULL PRIMARY KEY ); INSERT INTO __vw_custom_role_downgrade_guard (blocked) VALUES (1); -- The duplicate key aborts the revert. It is only inserted while the acknowledgement is absent. INSERT INTO __vw_custom_role_downgrade_guard (blocked) SELECT 1 WHERE to_regclass('__vw_allow_custom_role_downgrade') IS NULL; DROP TABLE __vw_custom_role_downgrade_guard; -- The previous schema exposes access_all as the three collection permissions together. Avoid -- turning Edit-only memberships into Create/Edit/Delete grants when rolling back. UPDATE users_organizations SET access_all = create_new_collections AND edit_any_collection AND delete_any_collection WHERE atype = 4; ALTER TABLE users_organizations DROP COLUMN create_new_collections; ALTER TABLE users_organizations DROP COLUMN edit_any_collection; ALTER TABLE users_organizations DROP COLUMN delete_any_collection;
