Hi, We are trying to use slony and WAL shipping for warm standby for replication with postgresql. Currently our systems are in oracle and we r checking the feasibility to migrate to postgres. Replication is one major issue here. Though everything seems to be working fine in our test environment, we just want the assurance that Slony and WAL shipping is used by other large production systems and running successfully. What are the other large 24x7 productions systems that use slony and the other WAL archiving of postgresql successfully?
