Correct, sudo is to perform a command as another user (by default
root, but it can be any user you which), while su is to 'become" that
other user (and then likely perform commands as that other user).

Only those few commands (in different scripts) need to be performed as
the database-owning user, all the rest of the process needs to be done
by root. Using sudo is the correct way to do that.
I will make sure to Depend on sudo.

Thanks for helping figuring this out.
