Fixes

• Fixed an issue causing global aggregations with JOINs on virtual tables (subselects) which contain LIMIT to return incorrect results. E.g.:

  SELECT COUNT(*) FROM
    (SELECT * FROM t1 ORDER BY a LIMIT 5) t1,
  JOIN
    t2
  ON t1.a = t2.b
  

• Fixed an issue that caused an error when trying to create a table with a generated column expression of type array.

• Fixed an issue that caused the account_user-column to be empty in the twitter tutorial plugin of the Admin UI.

• Fixed an issue when using GRANT/REVOKE/DENY statements on a table with a custom schema set. The statements would result in permission changed on the default doc schema.

• Fixed an issue with INNER and CROSS JOINS on more than 2 tables that could result in a Iterator is not on a row error.
