Re: Passing arguments to a function called by a trigger

>Is there a corresponding OLD as well if I ever want to do a trigger on
an UPDATE?

Yes, you are correct.

ODL is variable holding the old database row for UPDATE/DELETE operations in
row-level triggers and NEW is holding the new database row.

To get to know more about trigger just follow the tutorial at
http://wiki.postgresql.org/wiki/A_Brief_Real-world_Trigger_Example

I am sure u get more idea about it.
