I don’t really understand why you think this reverse inserted counting is
even a good idea so I don’t really care how laborious it is to implement
with existing off-the-shelf tools. A window function named “descending” is
non-standard and seemingly non-sensical and should not be added. You can
specify order by in the over clause and that is what you should be doing.
Mortgage payments are usually monthly, so order by date.
