Yes, they're different files. pg_service.conf is the global service file and .pg_service.conf the user-specific file in your home directory. > 2.

I would go with the user service file because it takes precedence over the system-wide file. The default path of the system-wide file only works on the database server where Postgres is running. What do you mean with "link with the database"? The service is file is read by libpq before opening a database connection. -- Erik
