What versions of PostgreSQL are you using? I've observed some
changes in the handling of serial columns in backup/restore from
version 7.x to 8.x. It is possible that your sequences aren't being
restored correctly. It would be pretty easy to manually set starting
sequence values. It is pretty hard to offer any concrete advise
without knowing what version of code you're running on both systems.
You might also tell us what platform(s) you are using.
