Hi Pedro, Would you let us know contents of your configuration files, hosts files, and debug logs. You can get debug logs when you start pgcluster with -lv option.

I tryed the configuration that you told me in the previous response and doesn't work, I have worst result than the configuration done before. The situation it's 3 db servers, with load balancer and replication server. I start all of them and do some insert and select to test the configuration, all it's works fine, all db are syncronized and have the same data. Then i poweroff one server and start it with -R option to have a dynamic recovery while i'm putting more data, but the results are so strage. The master db have all the insert, about 150, the second db was blocked and have no inserts!! the db that was recovering have 145 rows, lost five rows in the process. I think that it's a bug, because all it works fine until do the recovery with -R, if someone have this scheme working with dynamic recovery and without fail, please tell me how i have to configure that. If no one have this scheme i'll like to open a bug for this situation to improve this option because a partial recovery it's very bad recovery, worse than no recovery anithing.

The recovery follows the following actions, 1. All db data were copied to the target DB from the master DB as 1st rsync. 2. Sessions were brocked to the master DB and the target DB at load balancer. 3. All db data were copied to target DB from master DB as 2nd rsync. During 2nd rsync, these DB servers have to keep rsync only. During 2nd rsync, all sessions are executed at the 3rd cluster DB, and the data write queries (like INSERT, UPDATE) are put into queue files in the replication server. 4. Send stored queries to the master db and the target db from the replication server. Got it?
