Your best bet for running > 1 versions and / or > 1 clusters of the
same version, is to run debian or any debian based distro. You create
a new cluster like so:
pg_createcluster
Usage: /usr/bin/pg_createcluster [options] <version> <cluster name>
Options:
-u <uid> cluster owner and superuser (default: 'postgres')
-g <gid> group for data files (default: primary group of owner)
-d <dir> data directory (default:
/var/lib/postgresql/<version>/<cluster name>)
-s <dir> socket directory (default: /var/run/postgresql for clusters
owned by 'postgres', /tmp for other clusters)
-l <dir> path to desired log file (default:
/var/log/postgresql/postgresql-<version>-<cluster>.log)
--locale <encoding>
set cluster locale (default: inherit from environment)
--lc-collate/ctype/messages/monetary/numeric/time <locale>
like --locale, but only set for a particular category
-e <encoding> Default encoding (default: derived from locale)
-p <port> port number (default: next free port starting from 5432)
--start start the cluster after creating it
--start-conf auto|manual|disabled
Set automatic startup behaviour in start.conf (default: 'auto')
While RHEL is a solid and reliable OS, it was never built to run > 1
version etc of pgsql easily.
