> I've been finding performance issues when using a trigger to modify inserts on a partitioned table.

> The trigger is pretty simple:

> CREATE OR REPLACE FUNCTION quotes_insert_trigger()
> RETURNS trigger AS $$
> BEGIN
> EXECUTE 'INSERT INTO quotes_'|| to_char(new.received_time,'YYYY_MM_DD') ||' VALUES (($1).*)' USING NEW ;
> RETURN NULL;
> END;
> $$
> LANGUAGE plpgsql;

> I've seen that some of you guys have worked on writing triggers in C.

> Does anyone have had an experience writing a trigger for partitioning in C ?

> If you have some code to paste so I can start from I will really appreciate.

> Thanks
