BDR for PostgreSQL: Present and future

Craig's PlanetPostgreSQL
For a couple of years now a team at 2ndQuadrant led by Andres Freund have been working on adding bi-directional asynchronous multi-master replication support for PostgreSQL. This effort has become known as the BDR project. We're really excited to see these efforts leading to new PostgreSQL features and have a great deal more still to come. Incremental Development As a large development project it is neither practical nor desirable to deliver all the changes to PostgreSQL as a single huge patch. That way lies madness and unmaintainable code. It would also be resoundingly rejected by the PostgreSQL community, as it should be. Instead, BDR has been developed as a series of discrete changes to core PostgreSQL, plus an extension that uses those core changes to implement multi-master (more…)

Barman is finally out

Gabriele's PlanetPostgreSQL
It took longer than expected, but we have finally managed to release Barman as open-source under GNU GPL 3. Barman stands for "Backup and Recovery Manager" and it is an administration tool for disaster recovery of PostgreSQL servers. Currently only Linux systems are officially supported, however Python allows to plan porting and maintenance on different platforms as well. The idea of starting Barman began about a year ago. We were tired of managing disaster recovery solutions using custom scripts, hard to maintain and to monitor (you probably know what I mean). (more…)
