-    <para>
-      This section shows a sample configuration of a three-node cluster for the
-      <literal>myuser</literal> user and <literal>mydb</literal> database.
-    </para>
-    <para>
-      First, run the following commands on all cluster nodes:
-      <programlisting>
-# Switch to the 'postgres' user
-sudo su - postgres
-
-# Set up environment variables
-export PGHOME=/usr/pgproee-&majorversion;
-export PATH=$PGHOME/bin:$PATH
-export MANPATH=$PGHOME/share/man:$MANPATH
-export PGDATA=/var/lib/pgproee/&majorversion;/data
-
-# Create a new user 'myuser' with superuser priviledges
-psql --dbname=postgres --username=postgres -c "CREATE USER myuser WITH SUPERUSER ENCRYPTED PASSWORD 'myuserpassword'"
-
-# Create a new database 'mydb'
-psql --dbname=postgres --username=myuser --host=127.0.0.1 -c "CREATE DATABASE mydb"
-
-# Enable replication on all cluster nodes.
-# The 'trust' method in this example is only provided for
-# illustration purposes and is not recommended on production systems.
-sed -i '/md5$/s|host|#host|' $PGDATA/pg_hba.conf

-psql --exit
-
-# Restart &productname;
-sudo systemctl restart postgrespro-enterprise-&majorversion;.service
-</programlisting>
-</para>
-  <para>
-    Now create the <filename>multimaster</filename> extension on one of the nodes.
-    It will be replicated to all the other cluster nodes automatically.
-<programlisting>
