what is postgres?
I’m Nicola — PostgreSQL (Postgres) is an open-source, feature-rich relational database system supporting SQL, ACID transactions, concurrency, and extensible data types (JSONB, arrays, GIS via PostGIS). It’s widely used for reliable, scalable storage and complex queries in web apps, analytics, and geospatial systems.
