Clustering of pgsql 9.2 - Mailing list pgsql-admin

Dear All,

We have following environment for  database clustering at production environment:

1.       Postgres is running on RedHat 6 enterprise edition for primary and failover server

2.       SAN disk is available

Now I need help on following

1.       What should be clustering software used for Redhat clustering ? Can Veritas Clustering Software (VCS) clustering be used for clustering REDHAT OS?

2.       How the SAN disk can be used to store the data centrally? Can this be used as QUORAM disk?

3.       Is there any service for Postgres Database service clustering?

Please help me in providing details.

Regards
