You got it right: pg_service.conf is only used by libpq, so all clients that use libpq automatically support it. Other
clientsdon't support it.
For your examples that means:
- The PostgreSQL ODBC server can use pg_service.conf
- NpgSQL cannot use the file.

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
aconnectionstring that PostgreSQL ODBC will accept?
