Not really a Postgres related issue
From a security point of view your system is behaving normally because you
should not be able to execute root commands from a web browser
However if you have any C experience you may want to write a small script
that will setuid(0) i.e. root and then execute the command depending on
the argument that you give it.
Then put this file in /usr/local/bin
This should allow you to do what you want to do
