Hello,
I resolved this issue already.
The trigger now works fine.
I was looking at the wrong structure.
Thanks,
Peter

I have a trigger function written in C.
The trigger function is called via:
CREATE TRIGGER after_update AFTER UPDATE ON some_table
FOR EACH ROW EXECUTE PROCEDURE my_trigger_function();
Since the trigger is called after each row update the actual row data
should be available in some way to the trigger.
What functionality (SPI ?) do I use to use the column values from
the current row in the actual trigger?
See "Writing Trigger Functions in C" and "C-Language Functions" in
the documentation. Here are links to documentation for the latest
