As vector search becomes a foundational feature in modern applications—from semantic search and recommendation engines to AI-driven insights—developers are increasingly adopting PostgreSQL with the pgvector extension. However, one concept often creates confusion: the difference between similarity and distance.

At PGConf India 2025, I shared strategies for upgrading PostgreSQL replication clusters with no disruption to operations—highlighting examples and the evolving capabilities of logical replication.

Earlier this year, I had the pleasure of speaking at PGConf India 2025, where I presented on one of the most exciting advancements in PostgreSQL 17—how logical replication is now more resilient and failover-ready with failover logical slots—and today, I’m excited to share the slides from that talk with you.

In today’s cloud-native world, security isn’t just a checkbox — it’s foundational. When managing business-critical workloads like databases in Kubernetes, particularly with robust platforms such as Fujitsu Enterprise Postgres, ensuring secure access to sensitive information like credentials and TLS certificates is a must. This is where HashiCorp Vault comes into play.
