Trigger, record "old" is not assigned yet

Hi,

 

I’ve created a trigger BEFORE INSERT OR UPDATE on a table and, indeed, when the trigger is raised before insertion the record “old” is not assigned.  Is there a way to distinguish in the trigger procedure from an insert statement to an update statement?

 

Regards,

For plpgsql use TG_OP. See link below.

Or to be more specific:

IF (TG_OP = 'UPDATE') THEN
