Обсуждение: NEED REPLICATION SOLUTION -POSTGRES 9.1
Hi, We are planning to migrate our production databases to different servers.We have around 8 servers with 8 different clusters.We are planning t shuffle databases and make them as 7 cluster and migrate to new remote servers . We cannot use streaming replication as we are migrating different databases from different clusters to one single cluster . This will be resulting in huge downtime as data is huge . Need expert advice on this scenario.Can we reduce downtime in any way ..??

I'm using WAL, I follow this tutorial: http://blog.gomiso.com/2012/02/13/adventures-in-scaling-part-3-postgresql-streaming-replication/
It's work perfect for me, async replication.

The OP mentioned he couldn't use streaming as he is combining databases from multiple clusters into one, so non-streaming WAL isn't going to work any better for that. He needs to use Slony, Bucardo, or some other trigger based system (or roll his own) to accomplish this, WAL based solutions wont work.
