I am looking for a way to use a long/bigint primary key instead of the  
default integer id.

I did some googling and there are some results (e.g.  
[activerecord - How to use long id in Rails applications? - Stack Overflow](http://stackoverflow.com/questions/1066340/how-to-use-long-id-in-rails-applications)),  
but I am not sure about the solutions and I don’t want to have  
problems in a couple of months. Btw. I really want to use a standard  
mechanism and not a Rails hack, so that I can use the models without  
any special treatment.

Appreciate any help, Thanks.
