And that section says nothing at all about using 0 as a magic value. All
it says is:
"Let IC be the identity column of BT. When a row R is presented for
insertion
into BT, if R does not contain a column corresponding to IC, then the
value V for IC in the row inserted into
BT is obtained by applying the General Rules of Subclause 9.21,
“Generation of the next value of a sequence
generator”, to SG."
Which is pretty much what we do.
We can't implement everybody's way of doing serial cols, because they
are simply not all compatible. Next someone will be asking us to do it
MySQL's way (gods forbid).
