Also fixes: MDEV-21487: Implement option for mysql_upgrade that allows root@localhost to be replaced MDEV-21486: Implement option for mysql_install_db that allows root@localhost to be replaced Add user mariadb.sys to be definer of user view (and has right on underlying table global_priv for required operation over global_priv (SELECT,UPDATE,DELETE)) Also changed definer of gis functions in case of creation, but they work with any definer so upgrade script do not try to push this change.
