What is PostgreSQL?

An advanced open-source relational database known for its reliability, feature richness, and standards compliance.

PostgreSQL is a powerful, enterprise-class database supporting advanced features: JSON/JSONB for document storage, full-text search, window functions, CTEs (Common Table Expressions), materialized views, and custom types.

It offers excellent concurrency through MVCC (Multi-Version Concurrency Control), robust indexing options, and extensive extension ecosystem (PostGIS for geospatial, pg_trgm for fuzzy matching). It is the database of choice for many modern applications.
