Subject Descending FK index
Author Ivan Prenosil
What can be the consequences of combining Ascending PK index
with Descending FK index (or vice versa) ?

FB1.5 release notes say
"Caution - Make sure that foreign key and primary key indexes use the same sort order (DESC | ASC )."
but FB (2.x) will create it without complains, and it seems to work as expected too.
