PostgreSQL is not just an open-source relational database—it’s an enterprise-grade, extensible, and robust data platform trusted by some of the world’s largest organizations, including Apple, Cisco, and Instagram. Its powerful architecture, active development community, and unmatched feature set make it one of the most advanced open-source databases in existence. This Advanced PostgreSQL Training is designed for database professionals, system architects, DevOps engineers, and backend developers who want to take their PostgreSQL skills to the next level—far beyond basic CRUD operations and schema design. This course dives deep into the internals and advanced operational capabilities of PostgreSQL: • Architecture Deep Dive Learn how PostgreSQL processes queries, manages memory (shared buffers, work mem, etc.), and handles concurrency using MVCC. • High Availability with Patroni and etcd Set up and manage HA PostgreSQL clusters using Patroni, etcd, and HAProxy. Learn failover automation, monitoring, and switchover techniques. • Clustering and Streaming Replication Master synchronous/asynchronous replication, cascading replicas, and WAL tuning. Understand replication slots, timeline management, and failover strategies. • Performance Tuning & Query Optimization Dive into EXPLAIN ANALYZE, vacuum tuning, index strategy (BTREE, GIN, BRIN), and PostgreSQL-specific planner behavior. Learn how to analyze and tune slow queries and workloads. • Connection Pooling (PgBouncer / Odyssey) Learn how to handle high-concurrency environments using pooling layers, including tuning for OLTP and OLAP workloads. • Backup, PITR, and Disaster Recovery Planning Implement robust backup strategies using pg_basebackup, pgBackRest, and WAL archiving. Design disaster recovery plans for mission-critical systems. • Security and Hardening PostgreSQL Learn advanced role management, SSL/TLS encryption, row-level security (RLS), and PostgreSQL-specific attack mitigations. • Partitioning and Lar
