Can I have an example please? Or a link

create table trg_test (id integer, fld_1 varchar, fld_2 boolean);


CREATE OR REPLACE FUNCTION public.child_fnc(token character varying)
 RETURNS void
 LANGUAGE plpgsql
AS $function$
    BEGIN
        IF token = 'yes' THEN
            RAISE NOTICE 'Child';
        END IF;

CREATE OR REPLACE FUNCTION public.parent_fnc()
 RETURNS trigger
 LANGUAGE plpgsql
AS $function$
    BEGIN
        RAISE NOTICE 'Id is %', NEW.id;
        RAISE NOTICE 'Fld_1 is %', NEW.fld_1;
        RAISE NOTICE 'Parent';
        PERFORM child_fnc('yes');
    RETURN NEW;
    END;
$function$
;

create trigger test_trg before insert on trg_test for each row execute 
function parent_fnc();

insert into trg_test values (1, 'dog', 'f');
NOTICE:  Id is 1
NOTICE:  Fld_1 is dog
NOTICE:  Parent
NOTICE:  Child
INSERT 0 1

        Hello,

        Any idea or link are welcome. Thanks in advance


    sure, there is not any limit.
