Failover Solution for Postgres

Hello All

    I am looking for information on postgres failover solutions. I have
researched Dbmirror, DBcluster, and GFS along with others. This server
is running rh-postgresql-7.3.6 and Redhat ES 3.0 and I am trying to get
an idea of what is stable and reliable. What are people on this list
running for you failover solutions and what recommendations can you give
me. The server will be running about 9 databases anywhere form 350MB to
3GB. Looking to go live on the system 1st quarter 2005. I would love to
wait until postgres 8.0 is released and get the point-in-time recovery
along with the other features that will be in that version. But that
will have to wait.

Thanks
