What jumps out at me is those constraints.   The  PostgreSQL backend does
not currently support the forgien keys syntax nor the UNIQUE keyword.
However, they can be implemented using other methods.

For foreign keys, check out the contrib/spi directory.  (refint.* stuff)
The full syntax will be supported at some time in the future.

For unique, create a unique index on the necessary fields.

You should inspect and send the CommLog, so that we can determine exectaly
where the failure is occuring.    It can be activated in the DSN setup and
is located in D:\psqlodbc-*.log
