Oracle only see's 'postgres' db and no schema's vi HSODBC

Hi List;

 

We've established an Oracle HSODBC (Heterogeneous Services) connection to postgres. However no matter what database we specify in the postgres ODBC driver on the Oracle (windows) box Oracle only connects to the 'postgres' database. Also Oracle does not allow us to specify a schema name.

 

Any help? Comments? Thoughts???

 

Thanks in advance
