Hmmm... does nextval() 'hold' a sequence number for this backend? Otherwise,
the risk would be that you request a value, and someone else has beat you to
it before you insert it.

In any event, inserting then using currval() is the standard practice around
here, and it works great. Nothing fishy at all here, nothing to see, move
on.
