Would it be possible to have parameters in the SERIAL datatype?
CREATE TABLE x { ID SERIAL(100, 10) }
means ID starts at 100 and will be incremented by 10. And it would be
nice to have
CREATE TABLE x { ID SERIAL(0,0) }
mean that ID will be issued random non-repeating values (period=2^bitwidth
of type). This is most likely useful in replication/merging data.

You can create the sequence manually and define that a the default for
the column. I suppose we could pass the create sequence params through
SERIAL but there doesn't seem like there is much demand for it.
