Slony-I的删除：

接前篇：http://www.cnblogs.com/gaojian/p/3196244.html  

简单的Slony-I设置实例

 如何删除slony相关的内容呢。

我再另外找一台机器，安装slony，也安装postgresql（这个是为防止万一而已）

编写脚本：

[postgres@pg100 ~]$ cat remove.sh
#!/bin/sh

CLUSTERNAME=testdb3_cluster
MASTERDBNAME=testdb3
SLAVEDBNAME=testdb3
MASTERHOST=192.168.10.102
SLAVEHOST=192.168.10.101
REPLICATIONUSER=postgres

/usr/local/slony/bin/slonik <<_EOF_
    #--
    # define the namespace the replication system
    # uses in our example it is slony_example
    #--
    cluster name = $CLUSTERNAME;

    #--
    # admin conninfo's are used by slonik to connect to 
    # the nodes one for eachnode on each side of the cluster, 
    # the syntax is that of PQconnectdb in
    # the C-API
    # --
    node 1 admin conninfo = 'dbname=$MASTERDBNAME 
           host=$MASTERHOST user=$REPLICATIONUSER';
    node 2 admin conninfo = 'dbname=$SLAVEDBNAME 
           host=$SLAVEHOST user=$REPLICATIONUSER';

    uninstall node (id = 1);
    uninstall node (id = 2);
_EOF_
[postgres@pg100 ~]$ 

然后运行：

[postgres@pg100 ~]$ sh remove.sh
