Yeah, there is more we can try. First of all, we need to verify that Access
is actually calling SQLForeignKeys. Can you get a "trace" log of the
session? This would be the "sql.log" file which contains all api calls to
odbc. Make sure the file is clear beforehand. Then run the test. Quit
Access, turn tracing off and there's your logfile. You can send it to me.

It might also be helpful to have the commlog file (produced by the
driver)...usually "psqlodbc.log". It may have a process id number appended
to the filename so make sure you get the right one.
