mysql_fix_privilege_tables
This script updates all the mysql privilege tables to be usable by
MySQL 4.0 and above.

This is needed if you want to use the new GRANT functions,
CREATE AGGREGATE FUNCTION, stored procedures, or
more secure passwords in 4.1

Got a failure from command:
cat /usr/share/mysql/mysql_fix_privilege_tables.sql | /usr/bin/mysql --no-defaults --force --user=root --host=localhost --database=mysql
Please check the above output and try again.

Running the script with the --verbose option may give you some information
of what went wrong.

If you get an 'Access denied' error, you should run this script again and
give the MySQL root user password as an argument with the --password= option
