Postgres Per-Connection Statistics
I’ve had a wish list for a few years now of observability-related things I’d love to see someday in community/open-source Postgres. A few items from my wish list: As I’ve noted in a few places, there has been slow and steady progress in Postgres over recent years. There’s also plenty of good discussion continuing on … Continue reading
Challenges of Postgres Containers
Many enterprise workloads are being migrated from commercial databases like Oracle and SQL Server to Postgres, which brings anxiety and challenges for mature operational teams. Learning a new database like Postgres sounds intimidating. In practice, most of the concepts directly transfer from databases like SQL Server and Oracle. Transactions, SQL syntax, explain plans, connection management, … Continue reading
Kubernetes Requests and Limits for Postgres
As Joe Drumgoole said a few days ago: so many Postgres providers. Aiven, AWS, Azure, Crunchy, DigitalOcean, EDB, GCP, Heroku, Neon, Nile, Oracle, Supabase, Tembo, Timescale, Xata, Yugabyte… 🤯 I’m sure there’s more I missed. And that’s not even the providers using Postgres underneath services they offer with a different focus than Postgres compatibility. (I … Continue reading
Good Benchmark Engineers and Postgres Benchmark Week
There are four major components to being a good benchmark engineer: Apparently it’s benchmark week in the Postgres world. I only have two data points but that’s enough for me! First data point: I’m visiting Portland. This Thursday Aug 22, the Portland Postgres Users Group (PDXPUG) is having a meetup where Paul Jungwirth is going … Continue reading
Default Sort Order in Db2, SQL Server, Oracle & Postgres 17
TLDR: I was starting to think that the best choice of default DB collation (for sort order, comparison, etc) in Postgres might be ICU. But after spending some time reviewing the landscape, I now think that code-point order is the best default DB collation – mirroring Db2 and Oracle – and linguistic sorting can be … Continue reading
Major Developments in Postgres Extension Discovery and Distribution
PostgreSQL “extensions” are a big part of what makes this database special. The developers building the core Postgres database are amazing. But many people don’t realize just how much of a “data platform” Postgres is (borrowing this phrase from something Craig Kerstiens recently posted online) and just how decentralized the development is for PostgreSQL’s capabilities. … Continue reading
Postgres Indexes, Partitioning and LWLock:LockManager Scalability
I have decided that – in Postgres circles – I shall henceforth refer to 2023 as THE YEAR OF THE LOCK MANAGER’S REVENGE. Let me explain. Lets start with Bruce Momjian. He has an in-depth presentation about locking in general with PostgreSQL called “Unlocking the Postgres Lock Manager“. I see online that he’s been giving … Continue reading
UUID Benchmark War
This month’s PGSQL Phriday #015 topic is about UUIDs, hosted by Lætitia Avrot. Lætitia has called for a debate. No, no, no. I say let’s have an all-out war. A benchmark war. I have decided to orchestrate a benchmark war between four different methods of storing a primary key: The challenge is simple: insert one … Continue reading
Copy-and-Paste A New Postgres Dev Env In 5 Min
You can cut-and-paste the following commands to quickly get a new & clean dev environment for working with PostgreSQL source code. This includes Michael Paquier’s powerful script kit for managing the PostgreSQL development environment. Setting up from scratch takes me about 5 minutes, plus 3 minutes to configure, compile and install PostgreSQL for testing. Running the … Continue reading
Seattle Postgres User Group and PASS Summit – PGSQL Phriday #014
This month’s PGSQL Phriday #014 is about PostgreSQL Events, and it’s a great time to give an update about the Seattle Postgres User Group where I’ve been working together with long-time organizer Lloyd Albin. At the beginning of this year, I wrote about re-starting our meetups post-pandemic. This Thursday is our final meetup of 2023 … Continue reading
