I've been using the generate_series function and finding it very useful. It generates an integer, but I cast to 'day'
interval.
Might be useful.

Here is one idea a function, but is could be wrapped by one:
p2082849b=> INSERT INTO Testtable ( n, c, d )
p2082849b-> WITH RECURSIVE T(n,c,d) as ( SELECT 1, 'A', CAST(
'2009-12-31' AS DATE ) + INTERVAL '1 DAY'
p2082849b(> UNION ALL SELECT n + 1, c, d + INTERVAL '1 day'
p2082849b(> FROM T
p2082849b(> WHERE n <= 10000)
p2082849b-> SELECT n,c,d FROM T;
INSERT 0 10001
