The new binary replication protocols and tools in PostgreSQL 9.0 and 9.1 are a popular new feature - but they can also be used for other things than just replication! PostgreSQL 9.1 includes server changes to allow standalone tools to request and respond according to the replication protocol. From these, tools like pg_basebackup allow a number of new possibilities. And the infrastructure put in place in 9.1 opens opportunities for further enhancements - some already on the drawing board and some just wild ideas so far.
