Using PostgreSQL SERIAL to Create Auto-increment ColumnsUsing PostgreSQL SERIAL to Create Auto-increment Column. Summary: in this tutorial, you will learn about the PostgreSQL SERIAL pseudo-type and how to use the SERIAL pseudo-type to define auto-increment columns in tables.
Introduction to PostgreSQL sequences. 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.
