Sequence objects (also called sequence generators or
just sequences) are special single-row tables created with
<command>CREATE SEQUENCE</command>. A sequence object is usually used to
generate unique identifiers for rows of a table. The sequence functions,

provide simple, multiuser-safe methods for obtaining successive
sequence values from sequence objects.
