Subject Descending PK/FK index
Author Ivan Prenosil
Since FB1.5 it is possible to specify that automatically created PK/FK indexes
can be descending. The release notes also state

"Caution - Make sure that foreign key and primary key indexes use the same
sort order (DESC | ASC )."

Is this restriction still valid for FB2 ?
( I just created test tables and inserted some data just fine. Shoud I avoid
mixing Desc/Asc constraints anyway ? )
