I am trying to use "triggers". I get an error after "create trigger".
Does anybody know why?
create function insert_into_db2 RETURNS int AS
'/work/posgresql/lib/libpq.so' language 'C';
create trigger trial before insert or update on db1user for each row
execute procedure insert_into_db2();
ERROR: CreateTrigger: function insert_into_db2() must return OPAQUE
Does anybody know why?
Also, if a function is enforced to return OPAQUE then what is the
"RETURNS" clause?
One more question,
If a trigger does not succeed then I want to ABORT transaction, is
it possible? how?
