I guess I misread it... use the following:
- Import all the data into say an integer column.
- Now create a sequence and give it a start value of where your import ended.
- Make the default value for the column using the new sequence.

Is this possible/the best solution? Maybe a migration utility would be better? Suggestions?
Try using SERIAL datatype.
