RE: 'record old is unassigned yet' when using trigger in 7.1.1

When creating the trigger you need to specify BEFORE UPDATE rather than BEFORE INSERT.

Subject: 'record old is unassigned yet' when using trigger in 7.1.1

I have a function used in a trigger that looks like this:

begin
IF OLD.status <> NEW.status
THEN
NEW.statchangedate = CURRENT_DATE;
END IF;
return NEW;
end;

The problem is when a new row is inserted I get this error message:
ERROR: record old is unassigned yet
... and the insert fails.

It doesn't matter if the trigger is before or after.
