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
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

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

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
Did Postgres Lose My Data?
Hello, let me introduce myself. Today, we’ll pretend that I’m a linguistics researcher. I don’t know much about databases, but I do know a lot about the Balti language of northern Pakistan. That’s why I’m excited about my current translation project. The most interesting part of this translation project is that I’m doing some computer-driven … Continue reading
