Hi,
has anyone here had any good/bad experiences clustering & load balancing
a PostgreSQL server on Redhat (ES)?
i have two identical servers with plenty of memory plus a nice disc
array. the solution should have both redundancy and performance. BTW:
it's a back end to a web based application in a high traffic situation.
i thought it might be sensible to use a redhat cluster rather than
introduce another ingredient like PGCluster given we 'can' use a RH cluster.
any suggestions invited and appreciated.

We have recently successfully rolled-out a solution consisting of two
PostgreSQL database backends replicated by Slony. The backends are
accessed from a bunch of application servers (Apache) via pgpool. We
have some shell scripts around it to handle monitoring, failover and
switch-over. It is built on CentOS4 (ie. RedHat ES4). It's pretty solid.
