Hmm. That's a possibility. There's some potential for trouble if an
application is expecting an int4 result from "SELECT nextval()" and
gets int8 instead, but if we think we could live with that...
Actually, if we thought we could live with that, my inclination would be
to blow off int4-based sequences altogether, and just redefine SEQUENCE
objects as operating on INT8. Interesting thought, eh?
