+ Sequences are based on <type>bigint</> arithmetic, so the range cannot
+ exceed the range of an eight-byte integer
+ (-9223372036854775808 to 9223372036854775807). On some older platforms,

When <replaceable class="parameter">cache</replaceable> is greater than
one, each backend uses its own cache to store preallocated numbers.
