pgVis - Simple Visualisations For PostgreSQL

pgVis is a PostgreSQL extension for building simple visualisation dashboards with SQL. pgVis aims to make it easy to express data visualisations directly from SQL queries. Letting you quickly visualise some data for adhoc reports in psql or to build and share reporting dashboards in your organisation via pgvis-server. Either way, pgVis is designed to be PostgreSQL centric and to fit with your existing database workflows.


PostgreSQL - Not Just Relational

A Swiss Army Knife, which has so many uses

The extensibility of PostgreSQL is one of it's biggest advantages, making it capable of so many wide and varied usecases. Something that I've leveraged a lot on various projects, so much so that you probably don't need another database. Ryan mentions that it was extensions like PostGIS and hstore which brought him to PostgreSQL initially. For me it was TSearch2 (yeh, it was around 2008, it later got merged into core), then taking advantage of PostGIS, PL/Proxy, PGQ, JSONB and more over the years.


A PostgreSQL Backup Journey

Some broken hard drives, showing why you might need backups

I figured for PGSQL Phriday 002, that telling the story from when I looked after an energy insights database would be the most interesting way to talk about PostgreSQL backups. During the course of the project we used three differing backup tools and approaches, mainly driven by the ongoing exponential growth of the system. I also want to cover my biggest learning from that project. Which was something David Steele said at Make recovery part of your everyday processes.

The Isokon Gallery is a small visitor centre for the Isokon building in north London. For anyone into modernist architecture it's well worth a visit, staffed by volunteers who are really pationate about the building, they made the experience very memorable.


Langham Dome

The Langham Dome is a unique little museum in the site of a former WW2 Anti-Aircraft gun training dome. The dome was state of the art in WW2 with an innovative projection mechanism, showing footage of planes and a mounted gun which projected a crosshair over the footage.


HOT PostgreSQL

An elephant

A design goal of my monitoring system, Bergamot Monitoring, was to ensure that the monitoring state was persisted. As a long time PostgreSQL user, PostgreSQL was the obvious choice and it hasn't been a bad decision. An interesting aspect of monitoring systems is that they are constantly busy. Even a small scale deployment is likely to be executing one check every second. This translates to around two database updates a second.
