Nowadays, most Debian packages are maintained in Git repositories, with the majority hosted on Debian's GitLab instance at salsa.debian.org.Debian is running a "vcswatch" service that keeps track of the status of all packaging repositories that have a Vcs-Git (and other VCSes) header set. This status is stored in a PostgreSQL database, which is then utilized by Debian's package maintenance infrastructure for various purposes.

In my previous article on how to submit patches by email for PostgreSQL, I skipped over whether patches should be split up. Let’s discuss that now.

(See the previous article, as well as general Git documentation, for the technical details of how to split up a patch. Here, I’m only talking about why.)

Boy howdy that went fast.

There are several benefits to using temp tables in SQL DML operations. Given my long relationship and work on Oracle databases, I am highly familiar with the Oracle style “Global Temporary Tables” and have used them to solve many performance issues when complex joins are involved. That’s why I was excited when Gilles Darold released the extension “pgtt” for PostgreSQL. I was even more excited when Google released the extension for use in the Google CloudSQL for Postgres and AlloyDB for Postgres products.

Introduction – Invisible or Hidden Index.

Any database conversion offers valuable insights into how things work across platforms or how to achieve similar functionality in the target database. Invisible indexes are one such feature that is often requested in PostgreSQL when migrating away, due to their use case of create new or marking existing indexes as invisible for the optimizer.

Making indexes invisible can be beneficial for several use cases, such as:

In this post, let’s see how to control psql from outside with the coproc functionality in bash.

PostgreSQL Person of the Week Interview with Philip Marks: London boy, life long Arsenal fan! Married, two kids, well they’re both in their 20s now! Now currently living on the Welsh English borders in the hills, thank you broadband for finally getting there.

For PGSQL Phriday #016, Ryan’s asked us to “…discuss your process for tuning difficult queries. Specifically, try to focus on that one problematic query that really challenged you and you always use it as an example when helping or teaching others your methods.” Here are the generic steps I take, mostly in order. After that […]

The primary motivation behind boringSQL is to explore the robust world of SQL and the PostgreSQL ecosystem, demonstrating how these "boring" tools can cut through the ever-increasing noise and complexity of modern software development. In this series, I'll guide you through building a simple yet fully functional application—a Time Off Manager. The goal of this project is not only to demonstrate practical database/SQL approaches but also to provide a complete, extendable solution that you can immediately build upon.

Sometimes when we have an existing database and schema full of tables, there comes a time when we need to perform a migration. Maybe it’s because we want to move to or from a cloud service. Perhaps we have a small database and want to do a quick version upgrade via dump / restore. Whatever the reason, we may decide to clean up some technical debt while we’re making the transition.

Back on March 28, I asked the Postgres community whether new services for PGXN v2 should be written in Go, Rust, or “some of each”.

Last Tuesday (May 7, 2024) happened PGConf.BE in Leuven, Belgium. Living in Belgium myself, going to tech conferences in my own country is always a little bit special (and so much fun!).
While it was only the 4th time that the event was (very successfully) organized, and despite the attendance was not very high, this cozy conference still manage to have great line-up of talks every year!

Multi-master architecture has gained significant traction in the world of database management, offering a solution to traditional limitations in scalability, fault tolerance, and high availability. By allowing multiple nodes to operate as master, this architecture promises a more flexible and robust database system. However, along with these benefits come certain challenges, including data consistency, resource […]

I have just completed the first draft of the Postgres 17 release notes. It includes developer community feedback but still needs more XML markup and links.

Whether you are managing a large table or setting up automatic archiving, time based partitioning in Postgres is incredibly powerful. pg_partman’s newest versions support a huge variety of custom time internals.

The PostgreSQL Global Development Group has announced minor version updates to all supported PostgreSQL versions : 16, 15, 14, 13, and 12. These minor version updates introduce over 55 bug fixes that have been reported in recent months, reflecting PostgreSQL’s commitment to stability and performance. You might have seen our summary of PostgreSQL in 2023, […]

Learn how to optimize fill factor to boost database performance, minimize fragmentation, and balance storage needs.

The post Understanding PostgreSQL Fill Factor: Benefits, Drawbacks, and Best Practices appeared first on Stormatics.

Tuning Parameters vs. Tuning Queries is yet another talk that “almost made it” to a couple of conferences but ended up being on the reserve list, and I never had to present it anywhere except for Chicago PUG. And one more time, my friends at Microsoft are giving me a chance:)

Mapping Oracle Number Data types using any conversion tools has always been a topic of conversation that I’ve engaged in with my customers and partners. Schema conversion and data type conversion are among the first tasks we undertake once migration is initiated post-assessment. I have previously collaborated and contributed a detailed article on number data type mapping and its significance. Feel free to give it a read.

Coroot, an open source observability tool powered by eBPF, went generally available with version 1.0 last week. As this tool is cloud-native, we were curious to know how it can help troubleshoot databases on Kubernetes.In this blog post, we will see how to quickly debug PostgreSQL with Coroot and Percona Operator for PostgreSQL.PrepareInstall CorootThe easiest […]
