What's your time frame? The Hot Standby and Streaming Replication
features in PostgreSQL 9.0 will do exactly that. 9.0 is currently
in beta testing and expected to be released next month. These new
features are based on PITR techniques, but SR allows the WAL data
to flow across a connection in near real-time, and HS allows the
standby to be used for read-only queries.
