I have a pgpass.conf file that works well for my default user. It is in C:/Users/myuser/AppData/Roaming/postgresql/pgpass.conf. It reads like so;

localhost:5432:*:postgres:password1

I have a process that runs under the Administrator account. When I run whoami under this process I get nt authority/system. I want to be able to access the database from this process but it gets stuck because it needs a password. I have tried putting the above pgpass.conf into C:/Users/Administrator/AppData/postgresql/pgpass.conf and C:/Users/Administrator/AppData/Roaming/postgresql/pgpass.conf but it does not work. Is this the correct place for this file? Am I even able to do this as the Administrator. Unfortunately I cannot change the user that this process runs under.
