Robins Tharakan: FOR KEY SHARE optimization and the SLRU Trap

Neues vom PostgreSQL Planet - 10. Mai 2025 - 16:30
 FOR KEY SHARE optimization and the SLRU TrapOptimizing database concurrency is a constant balancing act. We often tweak locking strategies in PostgreSQL, aiming to allow more simultaneous operations without compromising data integrity. A common scenario involves shifting from stricter row-level locks to more lenient ones. But sometimes, what seems like a straightforward optimization can

Umair Shahid: Step by Step Guide on Setting Up Physical Streaming Replication in PostgreSQL

Neues vom PostgreSQL Planet - 10. Mai 2025 - 1:30

Physical streaming replication in PostgreSQL allows you to maintain a live copy of your database on a standby server, which continuously receives updates from the primary server’s WAL (Write-Ahead Log). This standby (or hot standby) can handle read-only queries and be quickly promoted to primary in case of failover, providing high availability and disaster recovery.

Umair Shahid: Improving PostgreSQL Performance with Partitioning

Neues vom PostgreSQL Planet - 9. Mai 2025 - 13:30

My recommended methodology for performance improvement of PostgreSQL starts with query optimization. The second step is architectural improvements, part of which is the partitioning of large tables.

Partitioning in PostgreSQL is one of those advanced features that can be a powerful performance booster. If your PostgreSQL tables are becoming very large and sluggish, partitioning might be the cure.

cary huang: Extending PostgreSQL with Java: Overcoming Integration Challenges

Neues vom PostgreSQL Planet - 8. Mai 2025 - 22:56
Why Bridge Java with C in the First Place?

Bridging Java and C combines the strengths of both languages. A C application may rely on Java for modern libraries, cloud APIs, or UI and web capabilities, while a Java app might need C for low-level system access or performance-critical tasks. Sometimes, there’s simply no alternative—certain features only exist in one language. While modern languages like C++ and Go offer both high- and low-level control, many systems aren’t written in them.

Lukas Fittl: Waiting for Postgres 18: Accelerating Disk Reads with Asynchronous I/O

Neues vom PostgreSQL Planet - 7. Mai 2025 - 9:45
With the Postgres 18 Beta 1 release this week a multi-year effort, and significant architectural shift in Postgres is taking shape: Asynchronous I/O (AIO). These capabilities are still under active development, but they represent a fundamental change in how Postgres handles I/O, offering the potential for significant performance gains, particularly in cloud environments where latency is often the bottleneck. Why asynchronous I/O matters How Postgres 17’s read streams paved the way New io_method…

Ahsan Hadi: Unleashing the Power of PostgreSQL with pgEdge Distributed Multi-Master Replication and Postgres Platform - Part 2

Neues vom PostgreSQL Planet - 7. Mai 2025 - 7:03

In this blog, we're continuing to explore the power of multi-master replication (MMR) with the pgEdge distributed Postgres platform and its open source extension, Spock. In the first Part 1 of this blog topic, we discussed different replication methods and deployment models for PostgreSQL replication.

Ahsan Hadi: Unleashing the Power of PostgreSQL with pgEdge Distributed Multi-Master Replication and Postgres Platform - Part 1

Neues vom PostgreSQL Planet - 7. Mai 2025 - 6:47

Before we delve into the main subject of this blog, it is essential to understand the benefits of PostgreSQL replication, and the difference between single-master replication (SMR) and multi-master replication (MMR). In every modern business application, the database is becoming a critical part of the architecture and the demand for making the database performant and highly available is growing tremendously.

Hans-Juergen Schoenig: CREATE INDEX: Data types matter

Neues vom PostgreSQL Planet - 6. Mai 2025 - 6:00

In the PostgreSQL world, as well as in order database systems, data types play a crucial role in ensuring optimal performance, efficiency, as well as semantics. Moreover, some data types are inherently easier and faster to index than others. Many people are not aware of the fact that indexes indeed make a difference, so let us take a look and see how long it takes to index the very same data using different
types.
