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
