Of course. I just wanted to know if there is a diference between using
order by field asc/desc regarding the way indexes are used in plans
when you execute a query. In Firebird when using order by desc it uses
the descending index if available if not then it uses natural scan with
sort descending. Does PostgreSQL use the ascending index both for
asc and desc order by?
Thanks in advance.
