error when running trigger (TG_OP not recognized)

error when running trigger (TG_OP not recognized)

(OP)
hi all.  i'm trying to write a generic trigger function that can be called by any trigger belonging to any table.  here's what i've got...

CODE

CREATE OR REPLACE FUNCTION process_table_activity_details()
  RETURNS "trigger" AS
$BODY$
DECLARE
    table_ident varchar(100);
    strsql varchar(1000);
    actionSet varchar(50);

BEGIN
    table_ident = 'qa.' || TG_TABLE_NAME || '_audit';
    IF (TG_OP = 'DELETE') THEN
        actionSet = 'OLD.*';
    ELSE
        actionSet = 'NEW.*';
    END IF;

    IF EXISTS (select * from all_qa_tables where table_name = table_ident) THEN
        strsql = 'insert into ' || table_ident || ' select now(), TG_OP, quote_ident(actionSet)';
    ELSE
        strsql = 'select now(), TG_OP, quote_ident(actionSet) into ' || table_ident;
    END IF;

    execute strsql;

        RETURN NULL;
    END;
$BODY$
  LANGUAGE 'plpgsql' VOLATILE;
ALTER FUNCTION process_table_activity_details() OWNER TO postgres;

when i run a query that activates a trigger that calls the above function, i get an error that "column tg_op does not exist".  i know that postgresql is case sensitive, so i assume it is reporting an error because the function is converting "TG_OP" into lower case when passing it in as a string to EXECUTE.  any ideas on how to get around this problem?

Maybe just put TG_OP outside the quots
