When PostgreSQL and 
Image Modified are not installed on the same machine (the database may be installed on any machine within the network), the database definition files need to be transferred to the PostgreSQL machine before the database can be created.
On the PostgreSQL machine (as postgres UNIX user): transfer the database-setup.tar file from the Image Modified machine and extract the files:
$ tar -xvf ./database-setup.tar
Set the permissions for the extracted files:
$ chmod -R 755 ./postgresql
