As a side point, I would recommend against doing this. Once you've
"used" a rowid, it's not worth reusing it. You'll save yourself some
headaches down the track if you simply ignore those odd gaps (ditto
the gaps that result from rolled-back transactions) and just DELETE
the rows you're throwing out without bothering to setval the sequence
back.
