Local variable and column name conflict

Hi,

Is there a way to specify a local variable/parameter within a query
where a column has the same name than the local variable/parameter?

Example:

CREATE OR REPLACE FUNCTION foo(i IN int) RETURNS void
AS $$
BEGIN UPDATE bar   SET i = i; // column i = parameter i
END;
$$ LANGUAGE PLPGSQL;

For instance, Ingres suggests prefixing local variable/parameter with
":" in the query:
 UPDATE bar   SET i = :i;

I can continue using the de facto Oracle's naming convention
(P_parameter and V_local_variable) anyway.  That's not a big deal.

Regards,
