 RETURNS void AS
$BODY$
DECLARE

Some code blocks

}
BEGIN

--> to here it is executing fastly after reaches this statement it's taking time


update table1 set col1 = val1 where pk = val2 and col2 = val3;


-----> HERE table1 IS HAVING THE TRIGGER I GIVEN BELOW THE TRIGGER( trigger1)


exception
WHEN OTHERS
 THEN
  raise notice '''EXCEPTION IN procname1 BLOCK 3 : %''',SQLERRM;
 NULL;
END; $BODY$
LANGUAGE 'plpgsql' VOLATILE;
ALTER FUNCTION procname1(args);




CREATE OR REPLACE FUNCTION trigger1()
 RETURNS "trigger" AS
$BODY$
BEGIN

IF (TG_OP='UPDATE') THEN
IF( some condition )
 THEN
  BEGIN
   INSERT INTO table2(cols)
   VALUES(values);
  IF NOT FOUND THEN
  NULL;
  END IF;
 EXCEPTION

Hi All,
I am having a trigger in table, If I update the the table manually trigger is firing immediately(say 200ms per row), But if I update the table through procedure the trigger is taking time to fire(say 7 to 10 seconds per row).

Please tell me what kind of changes can I make so that  trigger  fire
immediately while updating the table through procedure ?

Show us more details like source-code of the procedure, the trigger and
a demonstration.
