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 […]

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. […]

Intro GitHub Actions (GHA) are altogether a piece of excellent machinery for continuous integration or other automated tasks on your repo. I started to use them from the release day on as a replacement for CircleCI. Not that I think CircleCI is a bad product; I love to have everything in one place if possible. […]

PostgreSQL High-Availability has been one of the most dominant topics in the field for a long time. While there are many different approaches out there, Patroni seems to have become one of the most dominant solutions currently in use out there. Many database clusters are running on Linux. However, we have seen some demand for […]

Intro 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 new and fantastic feature asynchronous control […]

I wrote about the new pg_timetable 3 major release not so long ago. Two essential features were highlighted: – new session locking implementation – new jackc/pgx Golang library used Today I want to reveal one more advanced feature! Fasten your seat belts! First, we need to distinguish exclusive client session mode from exclusive chain execution […]

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 […]

¡Hola, queridos amigos! We’ve released several valuable features for pg_timetable in May. It’s summer already, and time is flying fast! I hope all of you are well and safe, as well as your families and friends. Here I want to introduce what’s new and how that is useful briefly. If you are unfamiliar with pg_timetable, […]

pg_timetable: Advanced PostgreSQL cron-like scheduler released! Hello there, this is your developer speaking… I’m struggling with how to start this post, since I’ve procrastinated a lot. There should be at least 5 published posts on this topic already. But there is only one by Hans-Jürgen Schönig. I’m thanking him for trying to cover my back, […]

This supposed to be just a short TIL entry about PSQL_EDITOR variable. While trying to figure out all possible pitfalls, I’ve decided to write a full blog post. You may skip to the summary though. All tests done on Windows 10 with PostgreSQL 12 installed. As you know, PostgreSQL ships with an interactive console tool […]

I’ve written already a blog post “Building PostgreSQL with MSYS2 and MinGW under Windows” a year ago. But this time I want to show you two important things: cross compiling (x86, x64) using the same run-time; compiling with the latest OpenSSL support.   That’s true nowadays you won’t find binaries or installations of PostgreSQL without […]

Years ago Years ago I wrote this post describing how to implement 1-to-1 relationship in PostgreSQL. The trick was simple and obvious: You put a unique constraint on a referenced column and you’re fine. But then one of the readers noticed, that this is the 1-to-(0..1) relationship, not a true 1-to-1. And he was absolutely […]
