After exactly half a year (seems to be a pattern already) since the last major release of pgwatch2 Open Source PostgreSQL monitoring tool, I’m glad to announce that another set of useful features and improvements have found their way into the pgwatch2 code repository! New version is incremented to v1.8.0 and content wise it’s mostly […]

The functionality of using table partitions to speed up queries and make tables more manageable as data amounts grow has been available in Postgres for a long time already, with nicer declarative support available from v10 – so in general it’s a known technique for developers. But what is not so uniformly clear is the […]

Usually in this blog I’m writing about various fun topics around PostgreSQL – like perhaps new cool features, some tricky configuration parameters, performance of particular features or on some “life hacks” to ease the life of DBA-s or developers. This post will be quite different though – inspired by an article I stumbled upon recently, […]

2 weeks ago we announced a new, long awaited, Postgres extension to look into execution plans for “live” running queries: pg_show_plans. This was not possible before in PostgreSQL yet, so it’s really a very cool piece of functionality and we’d like to echo out the message again. So here in this blogpost we’ll reiterate some […]

Recently I was talking in a more general way about some common auditing / change tracking approaches for PostgreSQL…but it also made me curious, how it roughly looks from the performance side? To quickly recap the previous blog post: the most common approaches for tracking important changes are mostly solved with writing some triggers. There […]

Recently, I was asked for advice on how to reasonably implement a common task of table change tracking – meaning a so-called “audit trail” for all row changes over time was required. The keyword “compliance” might also ring a bell in this context, here for those who work in finance or for government institutions. But […]

It’s been exactly half a year since the last major release of the pgwatch2 Open Source PostgreSQL monitoring tool, and I’m glad to announce that another huge set of useful features and improvements have found their way into the pgwatch2 code repository! The new version is incremented to v1.7 and, continuing the naming tradition, I’m […]

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 […]

Version 12 of PostgreSQL is not exactly fresh out of the oven, as the first minor release was already announced. However, I think it’s fair to say that this version can be still considered fresh for most users, and surely only a small percentage of users has upgraded. So I think it makes sense to […]

  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 […]
