What is SQLForignKeys in ODBC-Driver - Mailing list pgsql-interfaces

Hello,

I have a simple question: In technical information about the ODBC-driver
you can find the following:

---------------------
     Database protocols supported:   Postgres 6.2, 6.3, 6.4
(configurable by datasource)
  ...
      Extensions*:
         SQLExtendedFetch**
         SQLPrimaryKeys**
         SQLForeignKeys**

   ...
     **  see FAQ for additional information.
  ------------------------

The FAQ doesn't tell anything about this. I have looked into the
source-code an found some code for foreign keys.

Is  the a way to use foreign keys over an ODBC-link?

Kind regards,

Michael Contzen
