I have absolutely no use to update the ID. I'm not sure why anyone ever
would, and I guess I was a little shocked to find that PostGres even allows
it.
In MSSQL, an identity() is used instead of a serial, and once in place that
sucker is pretty much set in stone without a little know-how (it won't
happen by accident). I'm definitely not here for a "my way is better because
thats what I'm familiar with" discussion, just to get a feel of why its done
that way, if I'm doing anything wrong, or if there is an accepted way to
lock it down.
