PostgreSQL
PostgreSQL is an advanced open-source relational database known for its reliability, feature richness, and extensibility. It supports JSON/JSONB for semi-structured data, full-text search, and a vast ecosystem of extensions. In AI applications, PostgreSQL serves as the primary data store for application data, user information, conversation logs, and audit trails. With the pgvector extension, it also doubles as a vector database, enabling a single-database architecture for both relational and vector data. This simplifies infrastructure and reduces operational complexity.
