For more information about specific PostgreSQL property values, refer to the PostgreSQL database documentation. The erwin® Data Modeler documentation for the physical property editors provides brief descriptions of the controls on each dialog and tab, which you can use as a point of reference while working with database design features.
As a best practice, use the PostgreSQL ANSI ODBC driver for Reverse Engineering from Database (REDB) while using erwin® Data Modeler.

Defining PostgreSQL Objects

Follow these steps to create PostgreSQL objects and define their properties:

  1. In the Model Explorer, right-click the required object and click New.

    An instance of the object is created.
  2. Right-click the newly created instance and click Properties.

    The object's property editor opens.
  3. Set the values of all the required properties.

    For information on properties, refer to the corresponding object's property page from the above list.

  4. Click Close.
    The object is created and the required properties are set.
