PostgreSQL vs. Linux kernel versions

August 8, 2016/14 Comments/in 2ndQuadrant, Featured, PostgreSQL, Tomas' PlanetPostgreSQL /by Tomas Vondra

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 – […]

Tracing PostgreSQL with perf

November 4, 2013/2 Comments/in Craig's PlanetPostgreSQL, PostgreSQL /by craig.ringer

The profiling utility perf that ships with the Linux kernel is extremely useful for examining system-wide and multi-process behaviour – but it does a lot more than the CPU profiling it’s often used for. You’ve probably looked at perf top -az or perf top -u postgres output, but that’s only the littlest bit of what […]

Postgres and devops: testing 9.3 with Vagrant and Puppet – part one

October 2, 2013/4 Comments/in Gabriele's PlanetPostgreSQL /by Gabriele Bartolini

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 […]

Managing the backup of several PostgreSQL servers with Barman

December 4, 2012/2 Comments/in Barman, Gabriele's PlanetPostgreSQL /by Gabriele Bartolini

How to install multiple PostgreSQL servers on RedHat Linux

May 10, 2010/0 Comments/in Gabriele's PlanetPostgreSQL, PostgreSQL /by Gabriele Bartolini

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, […]
