/1 Comment/in Greg's PlanetPostgreSQL, PostgreSQL, United States News /by 2ndQuadrant PressThis week’s water falling from the skies isn’t turning into snow. And on days when it’s clear, my car is covered with tree pollen. While they means something different to most people, to me these are the signs that the spring conference season is about to start. There’s a conference in North America during each […]

Data generation and hardware quality
/0 Comments/in Greg's PlanetPostgreSQL, PostgreSQL, United States News /by 2ndQuadrant PressOne of the challenges when dealing with a new database design is that you don’t know things like how big the tables will end up being until they’re actually populated with a fair amount of data. But if the design has to factor in the eventual scalability concerns, you can’t deploy it to obtain that […]
Hinting at PostgreSQL
/8 Comments/in Greg's PlanetPostgreSQL, PostgreSQL, United States News /by 2ndQuadrant PressThis week’s flame war on the pgsql-performance list once again revolves around the fact that PostgreSQL doesn’t have the traditional hint syntax available in other databases. There are a mix of technical and pragmatic reasons behind why that is: Introducing hints is a common source of later problems, because fixing a query place once in […]
Tuning Linux for low PostgreSQL latency
/2 Comments/in Greg's PlanetPostgreSQL, United States News /by 2ndQuadrant PressOne of the ugly parts of Linux with PostgreSQL is that the OS will happily cache up to around 5% of memory before getting aggressive about writing it out. I’ve just updated a long list of pgbench runs showing how badly that can turn out, even on a server with a modest 16GB of RAM. […]

When that was written in the summer of 2008, a few months after the release of PostgreSQL 8.3, it was hard to find any similar guide that was both (relatively) concise and current. Since then, myself and […]

Particularly before the yum utility came about to help, getting RPM to do the right thing has often been a troublesome task. I was reminded of this again today, while trying to compile a PostgreSQL extension […]
