Hi I am trying to setup PGPool with native replication (ie: using PGPools replication functionality) and it doesn't appear to be working.
Server config
------------------
PGPool installed on 1 server
PGServer1
PGServer2
I insert data into the PGPool instance and data is only inserted into one PGServer1 and NOT the other PGServer2
My PGPool config is as follows:
-----------------------------------------
# - Backend Connection Settings -
backend_hostname0 = 'PGServer1'
backend_port0 = 5432
backend_weight0 = 0
backend_data_directory0 = '/postgres/data/'
backend_flag0 = 'ALLOW_TO_FAILOVER'
backend_hostname1 = 'PGServer2'
backend_port1 = 5433
backend_weight1 = 0
backend_data_directory1 = '/postgres/data'
backend_flag1 = 'ALLOW_TO_FAILOVER'
# - Replication settings
replication_mode = on
load_balance_mode = on
master_slave_mode = off
Also when I do a show pool_nodes it seems to indicate a master/slave setup? Is this correct? I have turned master/slave off .
> show pool_nodes;
node_id | hostname | port | status | lb_weight | role
---------+---------------------------+------+--------+-----------+--------
0 | PGServer1| 5432 | 2 | -nan | master
1 | PGServer2 | 5433 | 3 | -nan | slave
Does anything else need to be done to get PGPool native replication working? ie: not postgres streaming replication or do you need to have postgres replication enabled?
Thanks
Michael
