You have to specify this new cluster when you start postmaster with the -D option too or you can change it directly in the startup script like /etc/rc.d/rc.pgsql if you have one.

Thanks houdelou
This is what I did to get it to work (This was on CentOS 5.0)...
Shutdown postgres (if it's running)
Code:
root@host# service postgresql stop
Edit the start-up script
Code:
root@host# vi /etc/rc.d/init.d/postgresql
Change the PGDATA and PGLOG variable to wherever you want (changes in
red)...
Code:
# Set defaults for configuration variables
PGENGINE=/usr/bin
PGPORT=5432
PGDATA=/path/to/pgdata
if [ -f "$PGDATA/PG_VERSION" ] && [ -d "$PGDATA/base/template1" ]
then
echo "Using old-style directory structure"
else
PGDATA=/d2/pgdata
fi
PGLOG=/path/to/pgdata/pgstartup.log
# Override defaults from /etc/sysconfig/pgsql if file is present
[ -f /etc/sysconfig/pgsql/${NAME} ] && . /etc/sysconfig/pgsql/${NAME}
export PGDATA
export PGPORT
Create the directory...and set the permissions
Code:
root@host# mkdir -p /path/to/pgdata
root@host# chown postgres:postgres /path/to/pgdata
Initialize the database...
Code:
root@host# su - postgres -c "initdb -D /path/to/pgdata"
Now you can start postgres
Code:
root@host# service postgresql start
Now you can check this with the
ps and you'll notice (in
red) that the pgdata dir is where the database is
Code:
root@host# ps aux | grep post
postgres 11140 0.0 0.1 122556 3372 ? S 10:41 0:00 /usr/bin/postmaster -p 5432 -D /path/to/pgdata
