I realize this is just for demonstration purposes, but it's worth noting
that it doesn't actually guarantee that when you use the sequence to
populate a column in the table, the column would not have gaps.
Sequences are not transactional, so rollbacks will still produce gaps.
The documentation is misleading on that point. Without a strong
guarantee, it's a pretty useless extension.
