Just released version 0.3.0 of our tool for handling WAL based replication in PostgreSQL – OmniPITR.
Version jump is related to addition of another tool – omnipitr-synch. This tool is used to copy PostgreSQL data dir (including all tablespaces of course) to remote location(s).
While this process is usually simple (call pg_start_backup(), transfer data, call pg_stop_backup()), thanks to the tool it can be wrapped as single call, with standardized logging, and tested logic. It also makes it trivial, and cheap, to setup more than one new slave at a time, without need to read data off master more than once.
