Thanks for the prompt response,

Good to hear that, but really I cannot find a document how to configure Postgres as Failover on a 2 node MS cluster (one data store which could be owned by one node at a time and two Postgres Instances on both nodes one is active and the other is passive, just like oracle Failsafe on ms cluster), the available documentation is only mentioning the Replication and standby are the only choices for Postgres High availability and Clustering-Failover not.



Cheers
Adel

PostgreSQL has worked fine with the 2 node MS failover cluster since
the first native version on Windows, which was 8.0. You need no extra
software, and yo udon't need PostgreSQL 9.0 for it.

I share Simons recommentation that you *should* use PostgreSQL 9.0 or
9.1 though ;) And it also gives you other ways to build the
availability solution than the MS cluster one.

+1 :-)
