In its manual at - Creating Database Cluster -
they said to create a directory root?
already exists
and this is my 1 problem
the sub-directorys we have to create have to be under root of system?
in UBUNTU is impossible to look under root
then with initdb -D create a Cluster for data-bases, but it will be
accesible for the owner root, who will have access only to posgres
daemon, and the root of the system how control others daemons?
