Scaling AI Frontiers: Building Production-Ready RAG Applications with PG Vector on PostgreSQL
The rise of Generative AI has made Retrieval-Augmented Generation (RAG) a cornerstone for building intelligent, context-aware applications. While many solutions turn to specialized vector databases, this often introduces architectural complexity, data silos, and new operational overhead. What if you could build highly scalable, enterprise-grade RAG applications using the trusted, powerful, and familiar environment of PostgreSQL? This talk provides a comprehensive blueprint for leveraging...
Technical Deep Dive Into GitLab’s Database Load Balancer Architecture

Most of these tools involve having 1 primary database and a fleet of replicas which have some small amount of replication lag. Almost all of these solutions mean running multiple Postgres servers with the same amount of disk space, CPU and memory in order to ensure that any replica is ready for failover at any time. This increases the cost of your infrastructure but it can...
