these instructions are specific to RHEL 6/CentOS6 and assume you've
installed postgresql from the yum.postgresql.org repository.   all
commands run as root.   /path/to/new/data  must be owned by
postgresql:postgresql and have 700 permissions.

     cd /etc/init.d
     cp postgresql-X.Y postgresql-9.4B
     cd /etc/sysconfig/pgsql
     echo PGPORT=5433 > postgresql-9.4B
     echo PGDATA=/path/to/new/data >> postgresql-9.4B
     chkconfig postgresql-9.4B on
     service postgresql-9.4B initdb
     service postgresql-9.4B start
