avoid replace of column with variable in pgsql function

[Gerhard Heift <ml-postgresql-20081012-3518@xxxxxxxxx>]

Hello,

I have a function with an out variable in which I have an INSERT
statement with the same name as column. Is it possible to avoid the
replacement?

Its something like this:

CREATE FUNCTION insert_foo(IN bar integer, OUT id integer) AS
$BODY$
BEGIN
  INSERT INTO t1 (id, value) VALUES (bar, bar || '-bar');
  SELECT foo INTO id FROM t2 WHERE value = bar;
END
$BODY$ LANGUAGE 'plpgsql';

In the INSERT statemet the id column is replaced with $2, which is not
what I want. Quoting the colum name does not help. And I dont want to
rename the output variable nor the column of the table.

Is this possible?

Regards,
  Gerhard
