Load balancing in PostgreSQL distributes client connections across multiple database servers to improve performance, scalability, and availability. This guide compares Pgpool-II, ProxySQL, and HAProxy, covering their key features, advantages, limitations, and suitability for PostgreSQL workloads.

Revolutionize your database management with PostgreSQL 17! Experience faster, smarter, and more efficient backups with the power of incremental backup. Reduce storage, save time, and ensure seamless recovery – the future of PostgreSQL backup starts here!

This illustration represents the power of mysql_fdw in enabling smooth data exchange and real-time connectivity between MySQL and PostgreSQL. A perfect solution for cross-database operations and data integration!

Altering large tables in PostgreSQL can cause locks, performance issues, and downtime in production environments. This blog explains how pg_osc (PostgreSQL Online Schema Change) enables safe schema modifications using a shadow table approach, allowing applications to continue operating during migrations. The article covers how pg_osc works, compares it with alternatives like pg_repack, explores real-world use cases, and provides practical steps for implementing online schema changes in production. It also highlights best practices used by Mafiree to perform reliable zero-downtime PostgreSQL schema migrations in high-traffic environments.

Choosing the Right Replication Type in PostgreSQL – Understand the key differences between Streaming and Logical Replication, their best use cases, and how to implement them effectively for high availability, scalability, and disaster recovery.

Why memorize SQL queries when \d, \l, and \dx do the heavy lifting? Learn the power of PostgreSQL’s psql meta-commands today.

ProxySQL 3.0 introduces powerful capabilities like dynamic query routing, caching, multiplexing, and now PostgreSQL support. This blog explains how ProxySQL improves database performance, enables intelligent load balancing, and helps scale MySQL and PostgreSQL environments without application changes. Backed by real-world use cases from Mafiree, it provides practical insights into when and how to use ProxySQL effectively in production.

Explore the 8 critical changes in MySQL 8.4 you need to know before migrating your production environment. From authentication updates to InnoDB defaults, this release brings significant operational implications for developers and DBAs.

Cutting Query Time from 10 Minutes to Under 1 Second – How Functional Indexes Helped Us Optimize Aurora PostgreSQL and Stabilize CPU Performance.

PostgreSQL 18: Efficiency, security, and reliability, all in one upgrade

PostgreSQL uses a process-per-connection model, which can limit scalability in high-traffic environments. Connection poolers help manage this challenge by reusing database connections efficiently. This blog compares PgBouncer and Odyssey, two popular PostgreSQL connection poolers, highlighting their architecture, performance characteristics, configuration differences, and ideal use cases. It helps organizations choose the right pooling solution based on workload scale, complexity, and operational requirements.

MySQL features a unique tiered architecture that separates query processing from data storage through its pluggable storage engine model. This guide explores the core components—from connection handling and the SQL optimizer to the physical storage of data on disk. By understanding how engines like InnoDB provide ACID compliance and row-level locking, you can significantly improve your database's scalability. We also break down the query execution workflow and provide actionable tips for performance tuning, such as optimizing the buffer pool. Whether you're managing a replica set or a standalone instance, mastering MySQL’s internal structure is essential for building high-performance applications.

Understanding the difference between MySQL and PostgreSQL is critical when choosing a database for production workloads. While both are powerful open-source relational databases, they are built with fundamentally different philosophies. This comprehensive guide compares MySQL vs PostgreSQL across architecture, performance behavior under concurrent loads, replication strategies, and real-world use cases — backed by Mafiree's 17+ years of hands-on production experience across India, APAC, and the Middle East.

Schema changes on large MySQL tables can bring production systems to a halt if not handled correctly. This case study walks through how Mafiree helped a fintech client execute a zero-downtime MySQL schema migration on a 500M+ row production database — covering the real challenges faced, the three-phase tool strategy using gh-ost, pt-online-schema-change, and MySQL 8.0 INSTANT DDL, production configuration settings with performance benchmarks, and best practices for safely evolving your MySQL schema without impacting users

This blog explores PostgreSQL’s progress reporting system views that provide real-time visibility into long-running operations like VACUUM, ANALYZE, CREATE INDEX, COPY, and base backups. It explains how DBAs can monitor execution phases, estimate completion, detect bottlenecks, and improve operational efficiency using these built-in views. Real-world examples and use cases demonstrate how progress tracking enhances performance tuning, automation, and maintenance planning.

PostgreSQL 19 introduces REPACK, a native command that unifies the functionality of VACUUM FULL and CLUSTER while adding support for CONCURRENTLY to minimize downtime. Unlike traditional table rewrites that require long ACCESS EXCLUSIVE locks, REPACK can reclaim table bloat online by copying live data, rebuilding indexes, and applying concurrent changes before a final metadata swap. This article explores how REPACK works internally, compares it with VACUUM FULL and pg_repack, demonstrates a hands-on performance test, explains the new pg_stat_progress_repack monitoring view, and covers current limitations and best practices for production environments.

Understand how PostgreSQL streaming replication works, deploy a primary server and replica node, implement failover for high availability, and optimize your replication setup with Mafiree's expert DBA services. Ensuring high availability and data protection in PostgreSQL environments is critical for modern applications. One of the most effective ways to achieve this is through PostgreSQL replication setup, particularly using streaming replication with failover capabilities. This guide walks you through configuring a robust PostgreSQL replication system, covering everything from basic setup to handling failover scenarios.

Learn how to choose the right PostgreSQL index for better query performance. This guide explains B-Tree, GIN, and BRIN indexes, their ideal use cases, performance characteristics, and key indexing best practices to help optimize PostgreSQL databases efficiently.

PostgreSQL 19 introduces effective_wal_level, allowing logical decoding to be enabled dynamically when required, without changing wal_level or restarting the PostgreSQL server.
