Sequences in PostgreSQL are limited to bigint, there is nothing that can
be changed about that. But you are approximately the first person to
complain that the range of ids provided by bigint is too small, so maybe
it's worth reconsidering whether it would work for you. If it really is
too small, maybe a uuid would work. But yes, you'll need to make some
adjustments to the rest of your database or application code if you make
such changes.
