Not sure. But you can always avoid the OS authentication with empty user and password to access Oracle. You can use other authentication mode to access oracle instead.

And I have installed PostgreSQL and I want to migrate data from Oracle to PostgreSQL database. I have performed steps: CREATE EXTENSION oracle_fdw; CREATE SERVER oradb FOREIGN DATA WRAPPER oracle_fdw OPTIONS (dbserver ''); GRANT USAGE ON FOREIGN SERVER oradb TO postgres; CREATE USER MAPPING FOR postgres SERVER oradb OPTIONS (user '', password ''); Then I have created foreign table and I want to select from it. Unfortunatelly, oracle_fdw is unable to connect using OS authentication and it doesn??t work. Is it possible to use oracle_fdw to have OS authentication? Regards, Anna
