yes, cash_words(), it's deprecated.

not sure about that.

CREATE FUNCTION to_words(num integer) RETURNS text
AS $$
DECLARE
str TEXT;
BEGIN
str=cash_words(num * ('1.0'::money));
str=REPLACE(str,' dollars and zero cents','');
str=REPLACE(str,' dollar and zero cents','');
RETURN lower(str);
END;
$$
LANGUAGE plpgsql;

the type 'money' is deprecated, and the string 'dollar'
may be locale dependant so it's probably a bad idea to
do this. This is probably why cash_words is not
mentioned in the 8.4 manual.

May be a better approach, but you'll still need find/write
rulesets, and figure out how to call it from postgres.

if this is for printing cheques just listing the digits
is acceptable in my exerience

to_words(1234) => 'one two three four'

this can done using repeated (or nested) replaces.
