Jeff, hi:
1. my concern is global "event_trigger" for DDL, not per-table "trigger"
for DML
2. regardless - thank you for the link, I found it helpful
3. Tom Lane says event_trigger is just not implemented in plpython

Hello.
Problem:
1. any attempt to define python function as an event_trigger, i.e.:
CREATE FUNCTION public.verify()
RETURNS event_trigger
LANGUAGE 'plpython3u'
AS $$ print("hello-kitty") $$;
2. fails with message:
ERROR: trigger functions can only be called as triggers
SQL state: 0A000
3. here in the source:
https://github.com/postgres/postgres/blob/master/src/pl/plpython/plpy_procedure.c#L226
Question:
what is proper way to define python function as event_trigger?
Thank you.
Just do
"create function public.verify() as trigger..."
My bad--that should be "create function public.verify() returns
trigger... "
