Replication database postgresql 8.1

Dear all...

I need help to create replication database, I'ved tried use Slony-I but I think replication doesn't work.
I use this suggestion

========================
1. Create 2 databases, master, slave1 and ensure pl/pgsql is setup in each.
2. Create a pgbench schema in the master database:

> pgbench -i -U postgres master

3. Add a primary key called history_pkey to the history table on the tid, bid and aid columns.
4. Create a schema-only dump of the master database, and load it into slave1 and slave2:

> pg_dump -s -U postgres master > schema.sql
> psql -U postgres slave1 < schema.sql
> psql -U postgres slave2 < schema.sql

5. Create Slony config files for each slon engine (daemon on *nix). The files should contain just the following two lines:
for master.conf
---------------
cluster_name='pgbench'
conn_info='host=127.0.0.1 port=5432 user=postgres dbname=master'

for slave.conf
---------------
cluster_name='pgbench'
conn_info='host=127.0.0.1 port=5432 user=postgres dbname=slave'


Create a file for each database, adjusting the dbname parameter as required and adding any other connection options that may be needed.

6. (Windows only) Install the Slony-I service:

> slon -regservice Slony-I

7. Register each of the engines (this is only necessary on Windows - on *nix the slon daemons may be started individually and given the path to the config file on the command line using the -f option):

> slon -addengine Slony-I master.conf
> slon -addengine Slony-I slave1.conf

8. In pgAdmin under the Replication node in the master database, create a new Slony-I cluster using the following options:
9. Join existing cluster: Unchecked
10. Cluster name: pgbench
11. Local node: 1 Master node
12. Admin node: 99 Admin node

13. Under the Replication node, create a Slony-I cluster in each of the slave databases using the following options:
14. Join existing cluster: Checked
15. Server: <Select the server containing the master database>
16. Database: master
17. Cluster name: pgbench
18. Local node: 10 Slave node 1
19. Admin node: 99 - Admin node

20. Create Paths on the master to slaves, and on each slave back to the master. Create the paths under each node on the master, using the connection strings specified in the slon config files.

On Slave:
---------
Adding a new Master Path/listener:
a) Refresh and expand all items in the Replication tree
b) Right-click 'Path (0)', under 'Master Node'
and select: 'New Path' menu item
[Server: '2 - Slave Node' appears]
[Conn retry: '10' appears]
Enter: Connect info:
'host=127.0.0.1 port=5432 user=pelindo dbname=slave'
Click: OK

c) Click on Master Node: listens
[Note that a master listener is automatically added]

Adding a new Slave Path/Listeners:
a) Right-click 'Path (0)', under 'Slave Node'
and select: 'New Path' menu item
[Server: '1 - Master Node' appears]
[Conn retry: '10' appears]
Enter: Connect info:
'host=127.0.0.1 port=5432 user=pelindo dbname=master'
Click: OK
b) Click on Slave Node: listens
[Note that a slave listener is automatically added]

On Master:
---------
28. Create a Replication Set on the master using the following settings:
29. ID: 1
30. Comment: pgbench set

Adding a new master Path/listeners:
a) Right-click 'Path (0)', under 'Master Node'
and select: 'New Path' menu item
[Server: '2 - Slave Node' appears]
[Conn retry: '10' appears]
Enter: Connect info:
'host=127.0.0.1 port=5432 user=pelindo dbname=slave'
Click: OK
b) Click on Master Node: listens
[Note that a listener is automatically added]

Adding a new slave Path/listeners:
a) Right-click 'Path (0)', under 'Slave Node'
and select: 'New Path' menu item
[Server: '1 - Master Node' appears]
[Conn retry: '10' appears]
Enter: Connect info:
'host=127.0.0.1 port=5432 user=pelindo dbname=master'
Click: OK
b) Click on Slave Node: listens
[Note that a listener is automatically added]

Adding a new Replication Set:
Right-click 'Replication Sets (0)' and select: 'New Replication Set'
Enter: ID: '1'
Enter: Comment: 'Hardware'
Click: OK
Fully expand tree: 'Replication Sets (1)'

Adding a new table:
Right click: 'Tables (0)' and select: 'New Table'

32. Table: public.accounts
33. ID: 1
34. Index: accounts_pkey
35.
36. Table: public.branches
37. ID: 2
38. Index: branches_pkey

47. On the master node, create a new subscription for each slave using the following options:
48. Origin: 1
49. Provider: 1 - Master node
50. Receiver: 10 - Slave node 1
51. Start the slon service (or daemons on *nix):

I tried to insert data on table accounts (on database master), but data can't automatic replicate to database 'slave' that i have create before,
is the any wrong with mw configuration?
