I assumed/believed sudo was part of the "base" Debian system, as I don't have issues when building the package with pbuilder.
I indeed want to execute those commands as the user that owns the database.
I understood sudo (su DO) was meant to execute commands as another user, while su is used to "become" another user. Granted, with `su -c` you can execute a command as another user.
Extract from the manpages:
sudo:
sudo, sudoedit - execute a command as another user
su:
su - change user ID or become superuser
OPTIONS
-c, --command COMMAND
Specify a command that will be invoked by the shell using its -c.
I am wondering what the most appropriate command is to perform this task.
