Hmm ... 7.3 does have support for 64-bit sequences, if it was compiled
on a compiler that has a 64-bit integer type. If you just do
create sequence s;
select * from s;
what do you see for max_value? If it's 2147483647, then you need to get
a better compiler and rebuild Postgres. If it's 9223372036854775807
then you're good, and what you probably have is a sequence that was
dumped and reloaded from an older version of Postgres that didn't have
64-bit sequence support. I don't think 7.3 has ALTER SEQUENCE, but you
could drop and recreate the sequence and then manually fix its current
value.

Not unless you said CYCLE. Read the CREATE SEQUENCE man page.
