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 – […]

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, […]
