Docs: How to set Admin flag via DB access

[pglombardo]

You can directly access the database and set the admin field to true.

UPDATE users
SET admin = 1
WHERE email = '[email protected]';

Just be careful. Make sure only the accounts you want are marked as admin:

select email from users where admin = 1;

admin is a boolean column - you might have to use true instead depending on the DB type you are using.
