You got it right: pg_service.conf is only used by libpq, so all clients that use libpq automatically support it. Other clients don't support it. For your examples that means: - The PostgreSQL ODBC server can use pg_service.conf - NpgSQL cannot use the file. Yours, Laurenz Albe -- Cybertec | https://www.cybertec-postgresql.com Thank you Laurenz You mention that the PostgreSQL ODBC driver can use pg_service.conf. But I cannot find any examples om how to construct a connectionstring that PostgreSQL ODBC will accept? Regards Niels
