Those who dismiss this advice as my own imagination may want to check
how other server packages are installed on their system.
What user does sshd run under? Who owns /usr/sbin/sshd?
What user does the MTA run under? Who owns the binaries?
What user does Apache run under? Who owns the binaries?
etc.
On my system, the answer is sshd/postfix/www-data on the one side and
root on the other. Therefore it is consistent to use postgres and root
for PostgreSQL. If your system uses a different distribution of users,
you may want to adjust the PostgreSQL installation accordingly. But
note that this voids your warranty because it is not covered by the
installation instructions. :)
