I'm using Postgres 7.1.3, and I'm trying to set up a trigger. I have a last_updated column on all of my tables, that is of type timestamp. I want to set the field every time the record is updated. I thought a trigger would be best for that, but every example I find via Google doesn't work. One said to create a function that returned type TRIGGER, another said type VOID, neither of which worked. Every example I find uses one of those return types. Anyone have any ideas?
