I think it could work, but I don't think it is to be recommended. Sometimes
you want to log in as that user to be able to do certain types of special
administration or fixes. For example, if you ever need to run pg_resetxlog,
you probably want to be logged in as postgres, unless you are very confident
that your su or sudo invocations are correct and don't mess up the permissions
of the database directory in strange ways.
Maybe disabling the password of the account and allowing login only via sudo
is close to what you want, but ends up being more flexible.
