Обсуждение: can't CREATE TRIGGER

Hello

I can't create triggers, when I call for example:
ficha=> CREATE TRIGGER TRG_persons_id AFTER INSERT ON ficha_ofperson
ficha-> EXECUTE PROCEDURE add_person_id ( 'family_id', 'person_id' );

, the creation never finish and finally, after many minutes, I kill the
creation with Ctrl+c.
I try also a simple trigger creation with a function without arguments
and also the creation never finish.
 The functions work OK, I can call theme without problems, see below:
ficha=> select add_person_id (1,7);

 I also add a permissions as postgres user's, see below:
ficha=# GRANT TRIGGER ON TABLE ficha_ofperson TO PUBLIC;
GRANT

  So.., any Idea what is my error ???

   Thank you in advance,
             Gustavo

One possibility is that some transaction has a lock on the table which
would block the create trigger, do you have any long running transactions
or some kind of transaction pooling that might be keeping the table locked
for a long time? Can you create simple triggers on another table?

perhaps the table is locked, view in pg_locks...

You probably have an open transaction with a lock on ficha_ofperson,
so the CREATE TRIGGER statement blocks until that lock is released.
Query pg_locks to see what transaction that is.  Make sure your
applications don't keep transactions open longer than necessary.
