PostgreSQL Base and Composite Type Domains

PowerDesigner supports the following special PostgreSQL data types:

1. Select Model > Domains to open the List of Domains.
2. Click the Add a Row tool to create a new domain, and then click the Properties tool to open its property sheet.
3. Select either BaseType or CompositeType from the Stereotype list and click Apply .
4. An additional tab called either Base Type or Composite Type will be displayed, allowing you to specify type-specific extended attributes. See the relevant section in the PostgreSQL extended attributes section, for details of these properties.
