Using PostgreSQL SERIAL to Create Auto-increment ColumnsLearn how to use the PostgreSQL SERIAL pseudo-type to generate sequential integers for primary keys in tables. See examples, characteristics, and functions of SERIAL columns.
In PostgreSQL, a sequence is a database object that allows you to generate a sequence of unique integers. Typically, you use a sequence to generate a unique identifier for a primary key in a table. Additionally, you can use a sequence to generate unique numbers across tables.
