Structured, unstructured, semantic. When PostgreSQL, when pgvector, when Pinecone.

Structured, unstructured, semantic.
Relational databases (PostgreSQL, MySQL) are still the backbone of structured data. NoSQL systems (MongoDB, DynamoDB) make sense when schema and load call for them — rarely the case, for most products PostgreSQL is the right answer.
New in the toolbox: vector databases (pgvector, Pinecone, Weaviate, Chroma). They store embeddings — numerical representations of text, image, audio — and answer semantic similarity queries. The technical foundation of every RAG system.
