I am running ubuntu on a flash drive. The default log in is "ubuntu". I installed Postgresql and created a new user called "postgres". However, when I switch to postgres with "su postgres", the environmental path variable that I modified to be able to run psql from the terminal is gone. I'm guessing that postgres has it's own files to edit to change the PATH, but I don't know where it its? The .profile file that I can see from the GUI already has the PATH variable modified.
Thanks in advance.
