It is not defined. I know that this is not recommended. I was already thinking of defining it to be UTF-8 and than making backup and restore. Also, I was today thinking of defining 6 indices, each based on only one field of the current primary key and see what happens. Are these tests worth trying? > Is it reproducible ?

(My colleague and I have done numerous independent tests on various machines last week.) > What if you restore same backup at the another machine ? This was definitely done. No improvement. Please tell what would be your preferred FB version for these backup and restore tests. We have different versions on different machines, so I could see what can be done.
