I'm not a Mac person. But, on Linux, what I do is:
[shreyas@myapp(add_postgres_addapter)]$ sudo su - #change to root
[root@myapp(add_postgres_addapter)]# su - postgres # change to postgres
[postgres@myapp(add_postgres_addapter)]$ #do work as user postgres
[postgres@myapp(add_postgres_addapter)]$exit #return to root
[root@myapp(add_postgres_addapter)]# exit #return to my normal user
[shreyas@myapp(add_postgres_addapter)]$
Note that the above is just my editing of what I _think_ you _might_
see. The commands are correct. This assumes you have authority to do
the "sudo su -" to change to root. This is how I change to root
because it does not require that I use the root password. Once in
root, you can "su postgres" to change to the postgres user, without a
password.
Another possibility, again using sudo would be to change the password
on the postgres user like:
[user@system]$ sudo passwd postgres
Changing password for user postgres.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.
[user@system]$
