A property graph consists of three types of "things" in it: elements, labels and properties. 

Elements are nodes or edges in the graphs. They form the basic structure of a graph. An edge connects two nodes. Two nodes may be connected by multiple edges corresponding to different relationships between them.

Labels classify the elements. An element may belong to multiple classes and thus have multiple labels.

Introduction In certain situations, it can be beneficial to ignore integer overflow errors. Consider, for instance, an integer table column that typically accommodates small values. On rare occasions, a significantly larger value might be inserted. Attempting to aggregate these values could lead to an integer overflow error, causing the entire aggregate query to fail, which is far from ideal. Handling large values on the client or worker side, where the data is inserted, is one option.

Introduction – Implicit Conversion

Oracle to PostgreSQL migration is a playground that uncovers and touches upon many database concepts, which are always intriguing and fun to explore. Implicit Conversion, i.e., imposing automatic conversion on data types to make them comparable by database optimizers, is also a concept frequently encountered in database migrations. Implicit conversion allows for the automatic conversion of data types for an expression or condition when necessary for SQL execution, thus preventing failures.

1. Overview

In this blog post, we will guide you through the process of integrating IvorySQL, an open-source database built on PostgreSQL, into Neon Autoscaling Platform. Throughout this guide, we’ll walk you through each step, providing clear instructions and demonstrations.

Exploring new features in pgvector v0.7.0

Hacking on PostgreSQL is really hard. I think a lot of people would agree with this statement, not all for the same reasons. Some might point to the character of discourse on the mailing list, others to the shortage of patch reviewers, and others still to the difficulty of getting the attention of a committer, or of feeling like a hostage to some committer's whimsy.

There are many cases where external connection poolers like pgBouncer become unavoidable despite the costs and complexities associated with them. PgBouncer is one of the most popular external connection poolers for PostgreSQL. It is thin and lightweight, so it doesn’t have built-in authentication features like LDAP, which is essential for many enterprises. Luckily, pgBouncer has […]

Well that snuck up on me. Tomorrow, May 1 2024, Yurii Rashkovskii of Omnigres will be giving a presentation at the fifth installment of the Postgres extension ecosystem mini-summit. The tal, “Universally buildable extensions: dev to prod”, should provoke some interesting asymmetrical thinking and discussion.

Explore foundational parameters for maximizing the utility of PostgreSQL logs.

I wanted to write a “year-in-review” covering all the performance pgvector has made (with significant credit to Andrew Kane), highlighting specific areas where pgvector has improved (including one 150x improvement!) and areas where we can continue to do better.

The PG Day Chicago 2024 is over. For the last two days, I have been reading my LinkedIn and X feeds, which are full of mentions of PG Day Chicago. Everyone is happy and thankful.

Although I am busy “liking” all of these posts—not just “liking” but truly liking them—I didn’t blog anything myself. Two days later, I finally organized my thoughts to talk about that event.

The recent discussion about AIX support in PostgreSQL (as of now removed in PostgreSQL 17) led me to look through the project’s history, to learn what platforms we have supported when.

On April 23rd - after a very long break - the third PostgreSQL Meetup took place in Hamburg.

Sascha had temporarily taken over the Meetup group after the previous admins were no longer available. Last year at PGConf.DE 2023 I asked if there is anyone interested who would like to revive the group. Tobias had agreed to do so, and Lenz also joined the effort at the PGConf.EU 2023. After a few organizational details, the first (or rather third) meetup was scheduled.

Only Allow Login to Read-Replicas and StandbysWhen you're working with large databases in production, it is incredibly common to use read-replicas to improve performance. These read-replicas are a copy of your primary (main) database and let your applications offload read-heavy queries, which in-turn reduces strain on your primary database, effectively making the application faster and

As the database size increases and the number of transactions per second rise, you'll inevitably face the challenge of the table bloat. Although PostgreSQL assists as much as possible with its auto-vacuum feature, there will come a time when you will compel whether to run VACUUM FULL. Unless you have option of longish downtime windows, this is not an easy decision.

Remember this guy? Remember this guy? AI is all anyone talks about these days, isn’t it? Even when it comes to databases like Postgres, devs are finding new and innovative ways to leverage LLMs in everyday use cases. Can you really blame them though? This is an exciting new technology that will transform how we work and potentially society as a whole once it finally matures. We even covered building a crude RAG app a few short weeks ago.

Understanding and minimizing Postgres table bloat

My thanks to Jonathan Katz for his presentation, “Trusted Language Extensions for PostgreSQL”, at last week’s Postgres Extension Ecosystem Mini-Summit. As usual I’ve collected the transcript here interspersed with comments from the chat window. First, links!

The day before pgconf.de 2024 in Munich, a few of the Patroni project's contributors met to discuss the past, present and future of this framework for PostgreSQL HA. Various people and companies support and benefit from Patroni. Ants Aasma and I attended the meeting on behalf of CYBERTEC.
