1. upgrade to 8.2.5 asap
2. disable triggers is possible, but alter acquires an excl lock on
the table.  so, while you are disabling for you txn only, nobody else
does anything until you finish (is that what you want?)
3. there are other strategies to attack this problem for particular situations.

TIP 9: In versions below 8.0, the planner will ignore your desire to
       choose an index scan if your joining column's datatypes do not
       match
