I’ve published multiple benchmarks comparing different PostgreSQL versions, as for example the performance archaeology talk (evaluating PostgreSQL 7.4 up to 9.4), and all those benchmark assumed fixed environment (hardware, kernel, …). Which is fine in many cases (e.g. when evaluating performance impact of a patch), but on production those things do change over time – […]

Vagrant is a software that helps you build and configure virtual environments for development and testing purposes. Vagrant relies on virtual machine providers such as VirtualBox, VMWare and AWS, as well as provisioning tools such as Chef and […]
One of the key aspects of Barman is the possibility to remotely backup multiple PostgreSQL servers from one single backup host. The upcoming version 1.1.2 of Barman will make this much easier from a system administrator’s point of view. Let’s see why.
If you have a Linux server of the RedHat family (inclusing CentOS and Fedora), you might envy the way Debian/Ubuntu distributions handle PostgreSQL clusters management. Although it is not easy to install different PostgreSQL versions on the same RedHat Linux server using RPMs, it is much simpler to install several instances of PostgreSQL (servers) and, […]
