ERROR: cannot drop the currently open database

I heard a suggestion that I need to alter the pg_hba.conf but when I try to the system won't allow me because I don't have permission since its in the postgres group.

You don't need to modify the pg_hba.conf sine you can clearly connect. (It would not be telling you the role doesn't exist, but rather that you dont' have access from ip x.xx.xx.xx with user masteruser). YOu already seem to have a database with the same name as what the .sql file is trying to restore to. You probably want to run: drop database demo; But obviously be careful because you'll be erasing that database. You also need to not be connected from it, so connect to like, the default postgres database instead of "demo" when you're doing your restore.

If you know the script contains a drop database demo command then why are you connecting to an existing demo database to run it? You ask others what needs to be done yet the answer to that depends on what the script you are executing does and you haven't shared that script.
