Subject Generators and integer primary key fields
Author Federico Tello Gentile
Reading Interbase documentation I notice it says fields recieving
generator values must be int64. I'm using integer fields now.

Is the problem repeated values when I reach the integer limit?
I think the integer limit is 2^(32-1) - 1 (about 2 * 10^30) right?

I can switch to int64, but I don't plan to run out of integers in 10.000
years of using the application. Should I switch?
