PostgreSQL 9.1


New checkbox Unlogged added (verification changed accordingly).

Foreign Table

When Foreign Table is selected in the Table Type combobox, a new Foreign Table tab displays.

List of Options box should contain the part of CREATE FOREIGN TABLE command written in brackets in OPTIONS—e.g. filename 'c:\\file.txt'.

Although common entity object is used for Foreign Table entity in Toad Data Modeler, only the following features can be used:

  • Name
  • Schema

  • Attributes list
  • Comment
  • Permission
  • Foreign Server combobox
  • Foreign Table Options tab

For Attributes, only the following features can be used:

  • Name

  • Data Type
  • Null

Foreign Server

  • CREATE/DROP/ALTER are not supported
  • only a listing function


The Collation combobox is available for:

  • Data TypeText, Character varying(x), Character(x), Varchar
  • User Data TypeBase type with selected Collatable checkbox

  • Dictionary Type—if correct Data Type or User Data Type is selected (see above)

  • Domain—combobox is disabled (changes not allowed)


  • CREATE/DROP/ALTER are not supported
  • only a listing function

User Data Type—Composite Type

COLLATE collation definition can be used for every attribute to set its Collation. To set Collation, manually write COLLATE collation expression in Composite Type tab right after "attributename datatypename" definition (see the screenshot above). Toad Data Modeler will load it during RE.

No attribute is necessary for Composite Type.


It is possible to set Collation of every column/attribute of the table.

To set Collation

  1. Select the Generate Expression checkbox.
  2. In the Expression box, write e.g "atr1 COLLATE collname DESC, atr2".

Toad Data Modeler loads this index as an expression during RE.


Not Valid checkbox—option when you add a constraint of a foreign key.
