Embeddings are the foundation of vector search, allowing us to represent meaning-rich content like documents or queries as numerical vectors. But to use them effectively, it’s essential to understand what’s actually being embedded—whether that’s individual words, full sentences, or larger chunks of text.

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.
