You understood me perfectly well.
The data directory can either be created by "initdb", in which case
the mount point must allow the PostgreSQL user to create a directory.
You could set the group of the mount point to the group of the
PostgreSQL user and use permissions 1770, which should be perfectly safe.
Alternatively, the root user could create the data directory with the
correct ownership and permissions prior to running "initdb".
