Description: SERIAL pseudotype and related SEQUENCE object
Details:
It's possible that somebody already had found this thing, but I couldn't
find any references to this in archives.
We can create SERIAL field. But INTEGER type will be really set. It's well
known that INTEGER field doesn't match values more than 4 bytes. But related
SEQUENCE object has a 8 byte value.
It looks strange for me that 4 bytes of these 8 byte value will never be
used.
Is it bug or feature?
