It *is* an exact replica ... including having the sequence for the table be at
whatever number the original database is at. This is intentional and desired
behaviour.

After rebuilding the database, run:
SELECT SETVAL('inv_trans_id_seq', 1);
HOWEVER, I think you need some comprehension of Postgres sequences.
Fortunately, Justin has created a excellent animated flash tutorial on
sequences; see:
