Quite often when visiting customers or doing trainings, I see that people are quite happy seeing and learning about some little time-saving PostgreSQL tricks, commands or SQL snippets on the screen and they usually ask to slow down and explain or just say “wow, didn’t know you could do that”. As these tips and tricks […]

  With the latest major version freshly released, it’s again time to gauge its performance. I’ve already been doing this for years, and I have my scripts ready, so it’s not too much work for me – but rather, for the machines. The v12 release, as always, adds quite a lot of nice stuff. Some […]

Some weeks ago, in the light of PostgreSQL v12 release, I wrote a general overview on various major version upgrade methods and benefits of upgrading in general – so if upgrading is a new thing for you I’d recommend to read that posting first. But this time I’m concentrating on the newest (available since v10) […]

Soon it’s that time of the year again – basically a 2nd Christmas for followers of the “blue elephant cult” if you will :). I’m, of course, referring to the upcoming release of the next PostgreSQL major version, v12. So I thought it’s about time to go over some basics on upgrading to newer major […]

In order to prepare for the start of training season (you can see our “stock” training offerings here by the way), I’ve updated our small “Postgres features showcase” project, and thought I’d echo it out too. Main changes – coverage on some features of the current v11 release and also from the upcoming v12. Short […]

The above-mentioned PostgreSQL server configuration parameter was introduced already some time ago, in version 9.6, but has been flying under the radar so to say and had not caught my attention previously. Until I recently was pasted (not being on Twitter) a tweet from one of the Postgres core developers Andres Freund, that basically said […]

Having recently witnessed quite an ingenious hack to implement some good old “println” style development debugging from stored procedures into a file, it prompted me to post knowledge to the Interwebs on two other ways how such a goal can be implemented more transparently. Also, with help of some other good old legacy technology in […]

After almost half a year since last updates I’m glad to announce that another set of useful features and improvements have found their way to pgwatch2 – our Open Source PostgreSQL monitoring tool of choice. New version is incremented to 1.6 but continuing the naming tradition I’m also calling it “Feature Pack 5” as it’s […]

Needless to say, security is a topic that nobody in the wider IT industry can ignore nowadays, with a constant flow of reports on data breaches of various scales. Most of such cases don’t result from direct attacks against databases though, but more from targeting Application / API / Webserver problems as database servers are […]

First off – not trying to kindle any flame wars here, just trying to broaden my (your) horizons a bit, gather some ideas (maybe I’m missing out on something cool, it’s the most used Open Source RDBMS after all) and to somewhat compare the two despite being a difficult thing to do correctly / objectively. […]

Again I could make good (hopefully) use of the “slow time” around the turn of the year…and managed to push out another set of features for our Open Source PostgreSQL monitoring tool called pgwatch2 – so a quick overview on changes in this post. Continuing the tradition I’m calling it “Feature Pack 4” as it’s […]

It’s been already a bit over a month since the last Postgres major version was released (and also the 1st minor update is out) so it’s not exactly fresh out of the oven…and as usual there has been already a barrage of articles on the most prominent features. Which is great, as I can save […]
