[Cialug] Postgres trigger help.

[Tim Wilson]

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?
