According to the /etc/sysconfig/pgsql directory you're talking about, I
suppose you are on Fedora.

You need to create one init.d script by cluster and one file in the
/etc/sysconfig/pgsql directory per cluster.

Suppose I have a second cluster. I'll have to do this :

cd /etc/init.d
cp postgresql postgresql2
cd /etc/sysconfig/pgsql
cp postgresql postgresql2
$EDITOR postgresql2

In $EDITOR, I'll change the different environment values I want. For
example:
PGPORT=5567
PGDATA=/db/second_cluster

If I need a third cluster, I will do the exact same step but give a
different name for the init.d script (and also the PostgreSQL sysconf
file, don't forget they need to have the exact same name).
