Re: Postgres High Availablity Solution needed for hot-standby and load balancing

Hi Usama

yes, currently I am reading a brochure about Continuent uni/cluster for
PostgreSQL. Looks quite interesting.

Another product sounds promising: Cybercluster from www.postgres.at
English Product Description:
http://www.postgresql.at/picts/download/dokumentation/documentation_cybe
rcluster.pdf

Anyone has made experiences with it?


thanks
Ragnar

        Hi

        our customer has got the following requirements:

        Req1) Master master replication supported, not only
master / slave
        replication with only the master being writable. If you
do have multiple
        slave systems they are only useful from a backup and
standby
        perspective.  Our Application must have a db-connection
it can write to.

        Req2) Replication of schema should also be possible, not
only data

        Req3) Not only a hot-standby-solution is needed. Load
Balancing is
        wanted for the future.


        Currently I am looking at EnterpriseDB but it seems that
they dont
        support multiple master-replication

        best regards
        Ragnar
