Right. That's because the SERIAL type is a parser kludge rather than a
full-fledged type. At the moment, a column defined as SERIAL becomes,
in the parser backend, a defined sequence (CREATE SEQUENCE ...) and an
INT4 column with a constraint of DEFAULT ... which refers to the
sequence just created.
There are downsides to this: the implicit SEQUENCE is not cleaned up
if the column is destroyed; explicit reference to SERIAL is lost
during dump/restore; the implicit stuff just leads to confusion, etc
etc etc.
Perhaps eventually it should become a type on its own, directly
accessing the same structures as Vadim's "sequence" code. Or perhaps
it could be done using the SPI interface.
