This release contains previews of all features that will be available in the final release of pgwatch2 v1.9, though some details of the release could change before then. You can find information about all of the new features and […]

Our team is proud to introduce a new pg_timetable v4.4 release! This time we focused on implementing a couple of new features, as well as improving performance. I want to remind you that pg_timetable is a community project. So, please, don’t hesitate to ask any questions, to report bugs, to star the pg_timetable project, and […]

Hello, my name is Pavlo Golub, and I am a scheduler addict. That began when I implemented pg_timetable for PostgreSQL. I wrote a lot about it. In this post, I want to share the result of my investigations on the schedulers available for PostgreSQL. I gave a talk about this topic at the CERN meetup, so […]

© Laurenz Albe 2021 PostgreSQL v12 brought more efficient storage for indexes, and v13 improved that even more by adding deduplication of index entries. But Peter Geoghegan wasn’t finished! PostgreSQL v14 added “bottom-up” index entry deletion, which targets reducing unnecessary page splits, index bloat and fragmentation of heavily updated indexes. Why do we get index […]

Our team is proud to introduce a new major pg_timetable v4 release! This time a huge amount of work has been done and the pg_timetable v4 release is backward-incompatible with previous versions. However, job migration is straightforward and shouldn’t stop anyone from updating. We’ve added detailed Read the Docs documentation and will enhance it further. […]

zheap has been designed as a new storage engine to handle UPDATE in PostgreSQL more efficiently. A lot has happened since my last report on this important topic, and I thought it would make sense to give readers a bit of a status update – to see how things are going, and what the current […]

By Kaarel Moppel – I don’t usually post about upcoming PostgreSQL features and rather concentrate on tools available / versions released… but this feature, pg_read_all_data, got me excited and will certainly be a huge relief for real-life usage, especially for beginners! I had almost lost hope we might see this day – but after many […]

© Laurenz Albe 2021 Users with an Oracle background consider tablespaces very important and are surprised that you can find so little information about them in PostgreSQL. This article will explain what they are, when they are useful and whether or not you should use them. What is a tablespace Essentially, a tablespace in PostgreSQL […]

© Laurenz Albe 2021 PostgreSQL commit ee28cacf61 has added new options for the target_session_attrs connection parameter. This article explores how the new options can be used to simplify high availability and horizontal scaling solutions. What is target_session_attrs? The PostgreSQL client shared library libpq has support for connection strings to more than one database server: In […]

Intro – asynchronous chain execution in pg_timetable I wrote about the new pg_timetable 3 major release not so long ago. Three essential features were highlighted: new session locking implementation; new jackc/pgx Golang library used; exclusive chain execution. Meanwhile, two minor releases have come out, and the current version is v3.2. It focuses on the completely […]

© Laurenz Albe 2020 After all the technical articles I have written, I thought it would be nice to write about PostgreSQL sociology for a change. Language and community A community like PostgreSQL has no clearly defined borders. There is no membership certificate; you belong to it if you feel that you belong. That said, […]

As you probably know, pg_timetable is the advanced PostgreSQL cron compatible scheduler already released! Usually, any major release introduces absolutely new functionality as well as some backward incompatibilities. However, the only backward incompatibility present in this release is that the base task SHELL changed its name to PROGRAM. Yes, that’s all. 🙂 Now, let’s check […]
