Hmm.. I was trying simplify my function to get the point across with
minimal confusion. If you don't think there is enough detail, let me
know what is lacking and I will add the appropriate detail. The
function is executed BEFORE insert on table1. Thanks again for the help all

Here is my problem. I have a function that is triggered on insert. For
simplicity's sake, lets say the function looks like this:
CREATE OR REPLACE FUNCTION dostuff_on_insert() RETURNS TRIGGER AS '
DECLARE lockrows RECORD;
BEGIN
select into lockrows * from table1 where pkey_id = NEW.pkey_id for
update on table1;
update table1 set active = false where NEW.pkey_id = pkey_id and active;
NEW.active := true;
END;
'language 'plpgsql';
This is awfully vague. What table is the trigger placed on? (If table1
itself, seems like there are more efficient ways to do this.) What
events is the trigger fired for, and is it BEFORE or AFTER?
