Um, how would this be a bennefit? If you're inserting rows 101-259, how does
it benefit you to have the system automatically increment the sequence from
601-759?

FWIW, in 7.5 we're likely to implement SQL3 IDENTITY columns ... basically
just a SERIAL column where you don't have the option of inserting your own
value, you have to take what it gives you.
