Re: date range to set of dates expansion

The following code works in 8.4 but not 8.3.
Anyone know why, or what I need to do to change it?

SELECT aid, asid,      date_range (asdate, afdate)::date AS asdate,      acomments
FROM availability

In 8.4 it returns the expanded dataset as required. In 8.3 I get:

ERROR:  set-valued function called in context that cannot accept a set
CONTEXT:  PL/pgSQL function "date_range" line 4 at RETURN NEXT

Is there a way to use the integer only generate_series in 8.3 to generate 
dates by typecasting to/from integers?
