Small Clarification. I have gone through the documentation. I did not find any thing related to start ans stop replication after the replication is setup

1. If I shutdown the primary
2. Shutdown the slave
3. start Primary
4. start slave

Will this automatically catch up the streaming. Can you please comment?

Regards

Hi All -

        Need some help. We have been using postgres 9.0.4 for our production environment for some time. Today we are going to restart the Solaris servers. 

        We have streaming on . My question is how to handle the streaming when we start the database on the servers.

         Can you please give me some steps. I have actually used the http://wiki.postgresql.org/wiki/Streaming_Replication to set up the replication.

        Appreciate your help

Regards

So long as you leave your recovery.conf file in place, and don't loose any needed wal files between steps 3 and 4 (or
canrecover them from an archive), then the answer is yes.
