Razvan,
I don't believe there is a way of doing this from by way of some postgreSQL
command. We accomplish this by creating a table called "override". It is
defined as:
recid | integer | not null default
nextval('public.override_recid_seq'::text)
trig_name | character varying | not null
pid | integer | not null
batch | character varying | not null
Indexes:
"override_pkey" primary key, btree (recid)
"override_pid_key" unique, btree (pid, trig_name)
"override_pid_pkey1" btree (pid, batch)
We use this table to accomplish what you are talking about. We insert into the
table the trigger name, pid, and some made up string into batch. We use batch
so we can provide different levels of override, but you may not need that.
For the triggers we are interested in overriding, we code them to check for
the existance of a record in override that matches the trigger name and the
pid, and possibly, a batch name. If we find an override record, we simply
return.
Here is an example:
SELECT INTO ovrRec * FROM override WHERE
pid = pg_backend_pid () AND trig_name = name;
IF FOUND THEN
IF dbg THEN
RAISE NOTICE ''%: Overriding'', name;
END IF;
RETURN true; -- outa here
END IF;
RETURN false;
Actually, we put the above code into a function and call the function from
triggers that we may need to override from some other place.
Maybe some of the others have a better way. Hope this helps.

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to majordomo@xxxxxxxxxxxxxx)
