I am using PostgresPlus-8.4SS version of Postgres on Linux & Windows Systems. Now I need to enable replication of two servers. OS may be same or different.
Please let me know any useful links to do that.
I am not really sure what PostgresPlus-8.4SS is? but if you were using PostgreSQL 8.4 then Slony (http://slony.info/) can be a good option, otherwise upgrade to 9.0 and go with streaming replication which out-of-box.
