The isn module provides support for the international product numbering standards EAN13, UPC, ISBN (books), ISMN (music), and ISSN (serials).

The Greenplum Database isn module is equivalent to version 1.2 of the isn module used with PostgreSQL. There are no Greenplum Database or MPP-specific considerations for the module.

Installing and Registering the Module

The isn module is installed when you install Greenplum Database. Before you can use any of the numbering standards defined in the module, you must register the isn extension in each database in which you want to use the standards:

CREATE EXTENSION isn;

Refer to Installing Additional Supplied Modules for more information.
