Keith Fiske: Time Partitioning and Custom Time Intervals in Postgres with pg_partman
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.
Avi Vallarapu: PostgreSQL Minor version updates announced – May 2024
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, […]

Henrietta Dombrovskaya: I will be speaking at POSETTE: An Event for Postgres!
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:)
Deepak Mahto: Conversion Chronicles – Mapping Oracle Number Data types using AWS SCT and Ora2pg.
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.

Cady Motyka: Using Automatic DDL Replication with pgEdge Distributed PostgresQL
Until now, managing and updating Data Definition Language (DDL) schemas in PostgreSQL was a time-consuming, manual effort and especially difficult in a distributed environment. With the introduction of automatic DDL replication, pgEdge makes it easier and faster to deliver distributed applications built on open, standard-based PostgreSQL. In this blog, we delve into what Automatic DDL replication entails and how it can be leveraged effectively with pgEdge.
Paolo Melchiorre: Posette 2024
An Event for Postgres (pronounced /Pō-zet/, and formerly called Citus Con) is a free and virtual developer event. The name POSETTE stands for Postgres Open Source Ecosystem Talks Training & Education.
Laurenz Albe: cursor_tuple_fraction and the PostgreSQL JDBC driver
This article is a kind of failure story. I originally set out to write a piece about the PostgreSQL parameter cursor_tuple_fraction, only to discover that my boss has already covered that topic to some extent. Then I thought that I could investigate the parameter’s effect on the JDBC driver. That led me to an embarrassingly long wrestle with auto_explain and an eventual failure to find anything. But the world is littered with success stories, so why not share some failure?

Brandur Leach: The Notifier Pattern for Applications That Use Postgres
Listen/notify in Postgres is an incredible feature that makes itself useful in all kinds of situations. I’ve been using it a long time, started taking it for granted long ago, and was somewhat shocked recently looking into MySQL and SQLite to learn that even in 2024, no equivalent exists.
Henrietta Dombrovskaya:
At PG Day Chicago, I presented an extended version of my talk given last year at Citus.con – Temporal Tables and Standard. Just between the time my talk was accepted and I delivered the presentation, I learned that PG 17 would include the first-ever support of an important temporal feature: uni-temporal primary keys and unique constraints.

Radim Marek: How not to change PostgreSQL column type
One of the surprises that comes with developing applications and operating a database cluster behind them is the discrepancy between practice and theory, development environment and the production. A perfect example of such a mismatch is changing a column type.
The conventional knowledge on how to change a column type in PostgreSQL (and other systems compliant with the SQL standard) is to:
Ashutosh Bapat: Property graphs: elements, labels and properties
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.

Deepak Mahto: Conversion Gotchas: Implicit Conversion in Oracle to PostgreSQL Migration
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.
David Z: Bringing IvorySQL to Neon Autoscaling Platform
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.
