- The table_priv column of table_privs table was altered to a enum type
   with fewer enums causing the SHOW/CREATE VIEW grants to be truncated.

   are performed on each table
 - Reduced the number of ALTER's slightly, but as this is an upgrade script we need
   to take all possibilites into account.
